Authors: Göl Sevgi Can , Akbay Elif 
Published: November 2023

AbstractA series of TiO2/SBA‐15 photocatalysts were synthesized with different Si/Ti ratios by a one‐step hydrothermal method with TiO2 nano‐powder. During the synthesis of TiO2/SBA‐15 s, the SBA‐15 pore structure and channels did not deteriorate, and the Si/Ti molar ratios were close to the expected nominal ratios. Photocatalysts exhibited a uniform‐narrow pore size distribution, and the BET areas were in the range of 621–583 m2/g. TiO2 nanocrystals into the SBA‐15 mesopores walls achieve up to the ratio of Si/Ti=16. The optical band gap energies were significantly red‐shifted with increasing Ti insertion, which is the quantization effects improving the photocatalytic activities. The photocatalytic activities of the TiO2/SBA‐15 s were evaluated by the degradation of methylene blue under a UV‐light irradiation at a constant TiO2 content. The highest efficiency was obtained in the TiO2/SBA‐15(16) photocatalyst at 79.6 %. The results of reusability and stability analyses demonstrate that the photocatalyst activity and stability are good, and that the photocatalytic activity was sustainable after reuse for several cycles.

Authors: Divya  , Jangir Ritambhara 
Published: November 2023

AbstractCovalent organic frameworks (COFs) distinguish themselves from conventional materials by their exceptional combination of characteristics, including a well‐defined crystalline structure, inherent porosity, substantial surface area, remarkable design flexibility, capacity for functionalization, and chemical tunability. These attributes collectively contribute to the distinctiveness and versatility of COFs compared to traditional materials. This opens up exciting possibilities for multiple applications including energy storage, sensing, gas extraction and catalysis. The extraordinary stability of COFs in aqueous solutions and under harsh climatic conditions opens up new applications for them, including water treatment. COFs are attractive materials for tackling water pollution concerns and expanding their applications in related fields as a result of their distinctive attributes, like remarkable adsorption ability and adjustable architectures. The use of COF membranes in effluent management can improve the elimination of harmful dyes, resulting in better water quality and environmental protection. The creation of COF‐based membranes is a significant step forward in the field of water filtration and shows great potential for solving the issues faced by industrial wastewater contamination. Many published techniques provide continuous COF‐based membranes that fully utilize COFs for separations. Performance and characterization of COF‐membranes can be arbitrated with the help of various analytical and spectroscopic methods. The present study marks the most important structural characteristics and functional design methodologies of COFs in the form of thin membranes for dye separation. A discussion on the characteristics of COFs responsible for membrane separation with their synthesis and characterizations has also been done. Various reported fabrication methods of COF based membranes for dye removal are discussed concisely.

AbstractThe removal of inorganic and organic contaminants from wastewater is a crucial environmental concern, necessitating innovative and eco‐friendly solutions. This study introduces a novel and environmentally friendly approach employing Lippia alba leaves as an efficient adsorbent for the removal of lead metal ions and basic fuchsin dye from wastewater. Through a series of batch experiments, various parameters were explored, including pH, contact time, temperature, adsorbent dosage, and initial concentration, to better understand the adsorption process. The results were best described by the Freundlich model for lead ions and the Langmuir model for basic fuchsin dye, with maximum monolayer adsorption capacity (qm) of 67.06 mg/g (lead metal) and 33.32 mg/g (basic fuchsin dye). Kinetic studies demonstrated that the pseudo‐second‐order model accurately described the adsorption kinetics for both pollutants, while thermodynamics suggested exothermic adsorption for lead ions and endothermic adsorption for basic fuchsin dye, indicating spontaneous adsorption in both cases. Response Surface Methodology optimization achieved exceptional results: 99.9 % lead ion removal at 308 K, pH 4.5, 1.35 g/L adsorbent, and 2.5 mg/L initial concentration; 98.31 % basic fuchsin dye removal at 318 K, pH 6, 2 g/L adsorbent, and 15 mg/L initial concentration. This research offers a sustainable solution for water pollution challenges, supporting environmental preservation.

AbstractThe sensor 4‐(9H‐carbazol‐9‐yl)‐N,N‐dimethylbenzenamine, CNDMA a green fluorescent ligand developed for selective sensing of picric acid in DMSO/H2O (1 : 9) over different other nitroaromatic compounds. The sensing mechanism involves emission quenching significantly in the presence of picric acid with a color change from green to non‐fluorescent yellow. The sensing process drives through electrostatic and Hydrogen bonding interaction with formation of an Electron Donor‐Acceptor complex. In addition, inner filter effect also play role on the fluorescence quenching. The fluorescence quenching is a mixed‐type of both static and dynamic quenching process. The binding nature was figured out using the 1H NMR and FTIR titration studies. In addition the sensor showed good quenching efficiency and quenching constant with a lowest detection limit (LOD) of 5.09×10−8 M (R=0.99964) at 358 nm. Test strip experiment is demonstrated to understand the practical feasibility of the sensor.

AbstractNovelN,N‐disubstituted benzimidazolium salts were efficaciously synthesized in moderate to high yields and identified via1H NMR and13C NMR analyses. These compounds were tested on human liver cancer, prostate cancer, and normal embryonic kidney cell lines for 72 h. The results demonstrated that these compounds had antiproliferative activity. In particular, it was found that one of the compounds, 1‐(3‐chlorobenzyl)‐3‐(3‐methylbenzyl)‐1H‐benzo[d]imidazol‐3‐ium chloride, showed very high activity against liver cancer cell line and the IC50value of this compound was almost twice as low as the IC50value of cisplatin.

Abstract2D perovskites have attracted tremendous attention due to their superior optoelectronic properties and potential applications in optoelectronic devices. Especially, the larger bandgap of 2D perovskite means that they are suitable for UV photodetection. However, the layered structure of 2D perovskites hinders the interlayer carrier transport, which limits the improvement of device performance. Therefore, nanoscale structures are normally used to enhance the light absorption ability, which is an effective strategy to improve the photocurrent in 2D perovskite‐based photodetectors. Herein, a template‐assisted low‐temperature method is proposed to fabricate 2D perovskite ((C6H5C2H4NH3)2PbBr4, (PEA)2PbBr4) grating single crystal films (GSCFs). The crystallinity of the (PEA)2PbBr4 GSCFs is significantly improved due to the slow evaporation of the precursor solution under low temperatures. Based on this high crystalline quality and extremely ordered microstructures, the metal–semiconductor–metal photodetectors are assembled. Finite‐different time‐domain (FDTD) simulation and experiment indicate that the GSCF‐based photodetectors exhibit significantly improved performance in comparison with the plane devices. The optimized 2D perovskite photodetectors are sensitive to UV light and demonstrate a responsivity and detectivity of 28.6 mA W−1 and 2.4 × 1011 Jones, respectively. Interestingly, the photocurrent of this photodetector varies as the angle of the incident polarized light, resulting in a high polarization ratio of 1.12.

Consequently, the hybrid integration of soft and biomass‐derived materials shall store energy to mitigate intermittency issues, primarily through enthalpy storage during phase change. This paper introduces the recent advances in the development of natural biomaterial‐derived carbon materials in soft material assembly and its applications in multidirectional renewable energy storage. Various emerging biocarbon materials (biochar, carbon fiber, graphene, nanoporous carbon nanosheets (2D), and carbon aerogel) with intrinsic structures and engineered designs for enhanced enthalpy storage and multimodal applications are discussed. The fundamental design approaches, working mechanisms, and feature applications, such as including thermal management and electromagnetic interference shielding, sensors, flexible electronics and transparent nanopaper, and environmental applications of biocarbon‐based soft material composites are highlighted. Furthermore, the challenges and potential opportunities of biocarbon‐based composites are identified, and prospects in biomaterial‐based soft materials composites are presented.

Published: November 2023

AbstractBismuth chalcogenides are used as cathode materials in Zn‐proton hybrid ion batteries, which exhibit an ultraflat discharge plateau that is favorable for practical applications. Unfortunately, their capacity is not competitive, and their charge storage mechanisms are ambiguous, both of which hinder their further development. In this study, S‐doped Bi2Te3−x (SBT) nanosheets are prepared by tellurizing a Bi2O2S precursor using a hydrothermal process. As revealed by density functional theory analyses, the S dopant and its induced Te vacancies can distinctly manipulate the electronic structure of SBT, resulting in decent electrical conductivity and more negative adsorption energy to Zn2+. These advantages boost the Zn2+ storage ability of SBT materials. Consequently, compared with defect‐free Bi2Te3, the SBT cathodes have superior specific capacity, rate capability, and cycling stability.

Published: November 2023

AbstractOptimizing the active centers through reconstruction is recognized as the key to construct high‐performance oxygen evolution reaction (OER) catalysts. Herein, a simple and rapid in situ leaching strategy to promote the self‐reconstruction of NiFe‐layered double hydroxides (LDHs) catalysts is reported. The trace Zn dopants are introduced in advance by a facile and one‐step hydrothermal method, followed by leaching over the electrochemical activation process, which can remarkably reduce the formation potential of NiFeOOH active centers to enable the deeper self‐reconstruction for the formation of abundant highly active centers. Moreover, the self‐restructured NiFeOOH‐VZn cannot only significantly lower the dehydrogenation energy barrier for the transformation from Ni(OH)2 to NiOOH, but also decrease the free energy barrier of rate determining step for the *OH converted to *O through a deprotonation process, thus significantly boosting the OER behaviors. As a proof of concept, the obtained NiFeOOH‐VZn catalyst just requires a low overpotential of 240 mV at 10 mA cm−2, and delivers robust stability at 50 mA cm−2 over 120 h, which outperforms the benchmark of noble metal RuO2 and those of most non‐noble metal catalysts ever reported.

Published: November 2023

AbstractNormally, only noncentrosymmetric structure of the materials can potentially be piezoelectric. Thus, it is limited in the field of piezoelectricity for the centrosymmetric structure of the material. In this work, the performance of piezoelectricity is successfully achieved from centrosymmetric SrFeO3‐x by modulating oxygen vacancies, which have a surface piezoelectric potential up to 93 mV by using Kelvin‐probe force microscopy (KPFM). Moreover, the piezoelectric effects of SrFeO3‐x are also evaluated by piezoelectric catalytic effect and density functional theory calculations (DFT). The results show that the piezo‐catalytic degradation of tetracycline reaches 96% after 75 min by ultrasonic mechanical vibration and the production of H2O2 by SrFeO3‐x piezoelectric synthesis could reach 1821 µmol L−1. In addition, the DFT results indicate that the intrinsic effect of oxygen vacancies effectively promotes the adsorption and activation of O2 and H2O as well as intermediates and improves the piezoelectric catalytic activity. This work provides an effective basis for realizing the piezoelectricity of centrosymmetric materials and regulating the development of piezoelectric catalytic properties.

AbstractMultifunction superhydrophobic coatings that facilitate water harvesting are attractive for addressing the daunting water crisis, yet, they are caught in a double bind when their durability is considered, as durable coatings will require both tough micro‐textures to survive concentrated stress and high‐surface‐energy chemistry to form chemical bonds within the matrix. To date, a universal bulk‐phase coating that combines multifunctionality, ultra‐durability, and fabrication feasibility remains challenging. Here, a binary cooperative cell design is reported that can solve the contradiction between the multifunctionality and durability requirements of superhydrophobic coatings. In this strategy, mechanochemically tailored cells with releasable nanoseeds are infused in the common matrix, which serves both as a versatile chemical bridge to achieve strong bonds within the coating building blocks, and as an instantaneous self‐repairing generator to improve durability. Such a strategy significantly boosted the wear resistance and outdoor stability of the coatings by over 30–100 and 18 folds, respectively, compared with conventional coatings. The coating is applied to the sustainable application, i.e., enhancing the water collection efficiency by at least 1000% even after harsh abrasion. The strategy will broaden the vision in handling the dilemma properties among functional coatings and promote the application of superhydrophobic coatings in extreme environments.

AbstractSelf‐trapped excitons (STEs) typically give broadband photoluminescence emission with a large Stokes shift, which is important for the enhancement of the optical properties of materials. Here, low‐dimensional La‐doped BaTiO3 nanocrystals with defects are prepared using supercritical CO2 (SC CO2). The generation of the STEs is facilitated by doping La3+ ions and introducing CO2 pressure, which effectively enhance the luminescence intensity of BaTiO3. This discovery shows that the La ion doping concentration can modulate the photoluminescence of BaTiO3 nanocrystals under pressure. This work deepens the understanding of the influence of rare‐earth‐doped luminescent materials under pressure and provides insight to improve the capabilities of optical devices.

Published: November 2023

AbstractSustainable long‐lived room temperature phosphorescence (RTP) materials with color‐tunable afterglows are attractive but rarely reported. Here, cellulose is reconstructed by directed redox to afford ample active hydroxyl groups and water‐solubility; arylboronic acids with various π conjugations can be facilely anchored to reconstructed cellulose via click chemistry within 1 min in pure water, resulting in full‐color tunable RTP cellulose. The rigid environment provided by the B─O covalent bonds and hydrogen bonds can stabilize the triplet excitons, thus the target cellulose displays outstanding RTP performances with the lifetime of 2.67 s, phosphorescence quantum yield of 9.37%, and absolute afterglow luminance of 348 mcd m−2. Furthermore, due to the formation of various emissive species, the smart RTP cellulose shows excitation‐ and time‐dependent afterglows. Taking advantages of sustainability, ultralong lifetime, and full‐color tunable afterglows, et al, the environmentally friendly RTP cellulose is successfully used for nontoxic afterglow inks, delay lighting, and afterglow display.

Published: November 2023

AbstractSuperelastic aerogels with rapid response and recovery times, as well as exceptional shape recovery performance even from large deformation, are in high demand for wearable sensor applications. In this study, a novel conductive and superelastic cellulose‐based aerogel is successfully developed. The aerogel incorporates networks of cellulose sub‐micron fibers and carbon black (SMF/CB) nanoparticles, achieved through a combination of dual ice templating assembly and electrostatic assembly methods. The incorporation of assembled cellulose sub‐micron fibers imparts remarkable superelasticity to the aerogel, enabling it to retain 94.6% of its original height even after undergoing 10 000 compression/recovery cycles. Furthermore, the electrostatically assembled CB nanoparticles contribute to exceptional electrical conductivity in the cellulose‐based aerogel. This combination of electrical conductivity and superelasticity results in an impressive response time of 7.7 ms and a recovery time of 12.8 ms for the SMF/CB aerogel, surpassing many of the aerogel sensors reported in previous studies. As a proof of concept, the SMF/CB aerogel is utilized to construct a pressure sensor and a sensing array, which exhibit exceptional responsiveness to both minor and substantial human motions, indicating its significant potential for applications in human health monitoring and human–machine interaction.
