Tailored Supramolecular Self‐Assembly Nanoporous Carbon Toward Zinc Ion Hybrid Supercapacitor Application Zinc ion hybrid supercapacitors (ZIHCs), newly emerging energy storage devices, hold great potential for future energy storage applications. Proper design of porous cathode (c.a. porous carbon) to achieve efficient storage of hydrated Zn(H<sub>2</sub>O)<sub>6</sub> <sup>2+</sup> ions is one of the keys to improving its capacitive performance. However, although various strategies have been proposed to balance cost and performance, developing a carbon cathode synthesis strategy that concurrently optimizes both cost-effectiveness and efficiency remains nontrivial. Herein, to address this challenge, an innovative cost-acceptable supramolecular self-assembly strategy is explored to synthesize a molecular sieve type nanoporous carbon with reinforced nitrogen doping capability. In virtue of inventive "twin template" method, supramolecules in heavy bio-oil undergo targeted polycondensation and stack to form carbon fibers mesh with uniform nanopores around 10 Å. The DFT calculation confirmed its rapid transport of hydrated Zn(H<sub>2</sub>O)<sub>6</sub> <sup>2+</sup> ions. Concurrently, the in situ conversion of specific oxygenic groups in this scheme reveals an ideal reaction pathway for reinforced heteroatom functionalization. The KAc-MgCit-NPC sample with reinforced nitrogen doping exhibits a remarkable energy density increase of over 34%. This work opens a new avenue for developing high-performance carbon materials towards ZIHCs applications.

Covalent organic framework membranes for selective ion separation Ion-selective membranes play a crucial role in addressing water scarcity, environmental security, and energy utilization. Conventional microphase separation membranes suffer from trade-off limitation between permeability and selectivity due to the poor dimensional stability of ion-conductive regions. Microporous membranes utilize rigid polymer backbones to mitigate the trade-off effect, yet their tortuous pore connections hinder efficient ion separation. Covalent organic frameworks (COFs), known for their regular pore structures with permanent porosity and facilely tailored functionality, are anticipated as new-generation membrane materials. In this review, we elaborate on the potential and challenges of COF membranes from structural design, preparation protocols, and separation applications. Furthermore, we propose future opportunities and research trends for COF membranes, particularly in the scale-up fabrication, demanding ion separation system and genuine selective ion transport mechanism. Ion-selective membranes are essential for tackling water scarcity, environmental security, and energy challenges, yet conventional designs face a trade-off between permeability and selectivity. In this Review, the authors explore covalent organic frameworks as promising membrane materials, highlighting their structural advantages and proposing future research directions for enhanced ion separation and scalability.

Advanced electrochemical and photodegradation applications of ethylene glycol-functionalized boron nitride and molybdenum disulfide nanocomposites Abstract This study investigates the role of ethylene glycol (EG) and two-dimensional materials like boron nitride (BN) and MoS2 for advanced applications. EG enhances the integration and performance of these materials, while EG-functionalized BN combined with MoS2 improves properties. This research investigates the structural, optical and electrochemical properties of EG-BN/MoS2 (MOBN) composites, focusing on their interfacial synergy and functionalization. Characterization techniques such as Fourier transform infrared spectroscopy, UV–visable spectroscopy, Raman spectroscopy, X-ray diffraction and thermogravimetric analysis confirm the successful incorporation of MoS2 and BN, revealing a hybrid structure that enhances the composites’ stability and properties. The study finds that the MOBN2 exhibits superior thermal stability compared with MOBN1, with a distinct optical transition observed in the absorption spectra. Optical bandgap calculation shows values of 3.69 eV for MOBN2, emphasizing the influence of interlayer spacing and hybridization. Photoluminescence reveals improved optical properties in MOBN2, further confirming enhanced functionalization. Scanning electron microscopy images show a rough clustered surface morphology, while current–voltage curves demonstrate high reversibility and stability, showing quasi-rectangular curve characteristics typical of Electrochemical double-layer capacitors (EDLC) behaviour. From photodegradation analysis, it is observed that MOBN2 acts as a photocatalyst for the removal of methylene blue with an efficiency of 84%. Overall, MOBN composites exhibit enhanced optical, thermal and electrochemical performance.

Halogen dance reactions on thiophene derivatives Derivatives of thiophene play a significant role in the development of photoelectronic materials. Among the various modification methods for thiophene, the halogen dance reaction (HDR) represents an efficient strategy, as it addresses the challenge of activating the inert β-site of thiophene. Since the first example of HDR on 2-bromothiophene was reported in 1951, numerous halogenated thiophene derivatives have been found to undergo HDR with high efficiency. In this review, we provide a comprehensive overview of HDR on thiophene derivatives, ranging from single thiophene units to dimers and fused thiophenes, with the aim of highlighting this key methodology in thiophene-based chemistry.

Photosynergetic ligand-exchange for modular synthesis of copper nanoclusters The abundance, low cost, and distinctive properties of copper are driving increased interest in copper nanoclusters. However, modular synthesis of such clusters remains underdeveloped. Here, we report a modular strategy for constructing copper nanoclusters via the synergistic combination of photochemical activation and nanoscale ligand-exchange. Using a readily scalable precursor-[Cu<sub>14</sub>(TXP35)<sub>4</sub>(BnSe)<sub>12</sub>H]<sup>+</sup> (Cu<sub>14</sub>)-we demonstrate its photo-facilitated ligand-exchange with exogenous phosphine ligands, enabling the precise synthesis of 18 copper nanoclusters. This approach also allows functional motifs, such as chiral ligands, to be incorporated into the cluster framework. Mechanistic studies supported by in situ characterization reveal that upon light exposure, Cu<sub>14</sub> decomposes into diverse intermediates-including copper atoms/clusters, selenium, benzyl groups, TXP35, and their combinations-which then reassemble in the presence of external ligands to form new nanoclusters. Our modular nanosynthesis establishes a versatile platform for the atomic-level engineering of copper nanoclusters and is expected to advance the tailored design of cluster-based nanomaterials.

Визначення можливості отримання безбаластних Ni(II)-Ni(III) подвійно-шаруватих гідроксидів як перспективних активних речовин для суперконденсаторів та електрокаталізу This study is aimed to investigate the synthesis of Ni2⁺-Ni3⁺ LDH (layered double hydroxide) in the presence of sodium hypochlorite. Ni2⁺-Ni3⁺ LDH is a promising active material for use in supercapacitors and electrocatalysis. The syntheses were carried out at a temperature of 60°C by coprecipitation under conditions of high supersaturation and at constant pH values (8, 10, and 12). To obtain the guest metal cation Ni3⁺ from the initial Ni2⁺ during synthesis, sodium hypochlorite was introduced as an oxidizing agent into the alkaline sodium carbonate solution. As control samples, Ni-Al-carbonate LDH were synthesized using the same methods and conditions. The formation of Ni3⁺ hydroxo compounds during synthesis was visually confirmed by a color change. The crystal structure of the samples was investigated by X-ray diffraction analysis, and the total Ni and Ni3⁺ contents were determined by trilonometric and iodometric titration. The samples synthesized in the presence of hypochlorite exhibited a black color, confirming the successful formation of Ni3⁺ hydroxo compounds. All control samples corresponded to Ni-Al LDH. The nickel hydroxide sample synthesized by coprecipitation at high supersaturation was identified as β-Ni(OH)2, with a total Ni content of 59.5% and a Ni3⁺ fraction of 12.2%. The transformation of Ni2⁺ → Ni3⁺ occurred in the surface layer of the formed β-Ni(OH)2 particles because the oxidation rate was lower than the hydroxide formation rate. The samples synthesized by coprecipitation at constant pH exhibited a layered structure consisting of β-Ni(OH)2 and Ni2⁺–Ni3⁺ LDH with an α-type lattice, suggesting that the oxidation rate exceeded the hydroxide formation rate. Thus, the possibility of synthesizing Ni2⁺-Ni3⁺-carbonate LDH was experimentally demonstrated. Under the optimal conditions (pH 8), the proportion of the Ni-Ni LDH phase reached 55.9%. The synthesized Ni2⁺-Ni3⁺ LDH shows potential for application in supercapacitors and electrocatalysis, provided that its specific electrochemical characteristics are determined in further studies Coprecipitation ; Hydroxide ; Sodium hydroxide ; Sodium hypochlorite ; Oxidizing agent ; Hypochlorite ; Supersaturation ; Metal hydroxide Layered Double Hydroxides Synthesis and Applications ; Supercapacitor Materials and Fabrication ; Chemical and Environmental Engineering Research

Synergistic Intra‐ and Inter‐Nanozyme Electron Transfer through Interfacial Assembly for Enhanced Multi‐Enzyme Activity Prussian Blue composite nanozymes (PB C-NZs) have been extensively employed in various biomedical applications. However, due to the complexity of its multi-enzyme activities and structural components, designing material composition and processes, optimizing specific enzymatic properties of materials, and exploring the scientific mechanisms involved remain important challenges. Given the equal importance of electron transfer optimization and intrinsic redox properties, we propose an interfacial assembly strategy that leverages electron transfer and energy band structure, allowing for the synergistic interactions between internal and interfacial electrons of the nanocomposites (MoS<sub>2</sub>/PB) and thereby enhancing the enzyme-like activity. In the MoS<sub>2</sub>/PB system, a distinct inter-nanozyme electron transfer is operative, facilitating directional electron transport from MoS<sub>2</sub> to PB, thereby enhancing catalytic activity. Concurrently, band modulation effects induced by the interaction between MoS<sub>2</sub> and PB effectively enhance the reductase-like catalytic activity. Notably, the expression of multiple enzyme activities can be enriched through band regulation. The comprehensive enzymatic activity tests demonstrated that MoS<sub>2</sub>/PB exhibits enhanced multiple-enzyme activities, including catalase, peroxidase, superoxide dismutase, glutathione peroxidase, S-nitrosoglutathione reductase, and nitrite reductase. This study introduces a novel design concept for composite nanozymes based on electron transfer modulation, providing valuable insights and guidance for the development of high-performance nanozymes.

A Versatile Synthesis Approach and Interface Characterization of t-ZnO@Metal Hydroxide/Oxide Heterostructures Functional ceramics play a key role in technology, particularly in piezoelectric sensors and actuators, ferroelectric power generation, and durable semiconductors used in sensors and memristors. In this study, we report a versatile wet chemical synthesis approach, converting the surface of functional tetrapodal zinc oxide (t-ZnO) to common metal hydroxides. We performed structural, morphological, and interface characterization and explored the subsequent application of various t-ZnO@metal hydroxide/oxide core-shell structures. The t-ZnO core was initially uniformly coated with different metal hydroxides, forming distinct platelets in a core-shell architecture. Interface studies were conducted to investigate the chemical, structural, and morphological properties of these hybrid microstructures using 2D scanning nano X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), bulk XRD, X-ray photoelectron spectroscopy (XPS), and Raman spectroscopy. Our findings highlight the potential of exceptional t-ZnO structures as versatile templates, offering their morphology for the synthesis of derived oxides and hydroxides of many other elements while leveraging their structural advantages.

Morphology-Driven SERS Activation in TMDCs: A Dual-Mode Platform for Sensorics and Theranostics The development of reproducible and stable plasmon-free substrates for surface-enhanced Raman scattering (SERS) is critical for practical applications in analytical chemistry. Transition metal dichalcogenides (TMDCs) have emerged as promising candidates due to their unique electronic properties, yet their performance is often constrained by the chemical inertness of their pristine basal planes. This work presents a systematic comparison of crystalline flakes and nanoparticles of tungsten diselenide (WSe2) and tungsten ditelluride (WTe2), prepared via liquid-phase ultrasonic exfoliation and non-equilibrium femtosecond pulsed laser ablation in liquid (PLAL), respectively. The results demonstrate that nanoparticle-based substrates consistently outperform their flake-based counterparts, achieving enhancement factors in the range of 104. The superior performance of the nanoparticles is attributed to the synthesis-induced defects and high-curvature regions in the nanoparticles shell which facilitates efficient, defect-mediated charge transfer between the substrate and the analyte. At the same time, the inner polycrystalline volume conserves the important characteristics of the bulk counterparts like excitons in semiconducting WSe2 and broadband absorption in semimetallic WTe2, which unblocks the tunable photothermal colloidal response. The study establishes morphology engineering through non-equilibrium synthesis as a powerful and generalizable strategy for designing high-performance, dual-function colloidal platforms, offering a pathway toward robust and reproducible analytical systems.
