title: Influence of doping nitrogen on the catalytic performance of carbon nanotubes encapsulating cobalt for selective oxidation of arylalkanes
title: Influence of doping nitrogen on the catalytic performance of carbon nanotubes encapsulating cobalt for selective oxidation of arylalkanes

description: Efficient selective oxidation of hydrocarbons to corresponding ketones has been a significant but challenging work in the past decades. Here, a nitrogen-doped bamboo-like carbon nanotubes encapsulating cobalt catalyst (NCNTs-X) using citric acid, melamine and CoCl2‧6H2O as precursors was synthesized by a simple pyrolysis method. A series of characterization techniques were employed to investigate the physicochemical properties of samples. And the results show that the as-prepared catalysts achieve a high catalytic performance for selective ethylbenzene oxidation (78.3% ethylbenzene conversion) using molecular oxygen as oxidant, especially giving a high selectivity (93.8% selectivity to acetophenone). According to the investigation of the structure-activity relationship of the catalysts, it can be deduced that the Co–Nx sites have an obvious positive effect on catalytic performance thanks to the synergistic effect between metallic cobalt and pyridinic N.

title: Recent progress in sulfur cathodes for application to lithium–sulfur batteries
title: Recent progress in sulfur cathodes for application to lithium–sulfur batteries

description: Owing to the extensive use of fossil fuels for energy, environmental problems are becoming increasingly severe. Therefore, renewable clean energy sources must be urgently developed. As an environmentally friendly electrochemical energy-storage system, lithium-ion batteries (LIBs) are widely used in portable devices, electric vehicles, and medical equipment. However, owing to their high cost and low theoretical energy density, LIBs are far from meeting the current energy demand. Lithium–sulfur batteries (LSBs) (wherein lithium metal and sulfur are the anode and cathode, respectively) are one of the most valuable secondary batteries because of their high theoretical energy density (~2600 Wh·kg–1). However, the intrinsic conductivity of sulfur cathode materials is poor, and the lithium polysulfide formed during lithiation dissolves easily. Moreover, the volumetric expansion during charging and discharging adversely affects the LSB electrochemical performance, including the rate performance, cycle life, and coulombic efficiency. Therefore, to improve the LSB electrochemical performance, various sulfur composites have been prepared using carbon materials, metallic oxides, and conductive polymers, and various composite cathode materials recently developed for application to LSBs were reviewed. Finally, research directions were proposed for modifying LSB cathode materials.

title: Lanthanum-doped α-Ni(OH)2 1D-2D-3D hierarchical nanostructures for robust bifunctional electro-oxidation
title: Lanthanum-doped α-Ni(OH)2 1D-2D-3D hierarchical nanostructures for robust bifunctional electro-oxidation

description: The development of advanced electrocatalysts for electro-oxidation reactions has attracted much attention because of the critical role of such electrocatalysts in improving the overall efficiency of coupled hydrogen production. We have developed an efficient lanthanum-doped α-Ni(OH)2 bifunctional catalyst with a 1D-2D-3D hierarchical nanostructure. It shows superior activity and stability in the anodic oxygen evolution reaction (OER) and urea oxidation reaction (UOR). Enrichment of the edge sites and conducting La doping in α-Ni(OH)2 phase enable formation and stabilization of abundant local Ni3+ ions. This guarantees ultralow onset potentials in electro-oxidation reactions. The 1D-2D-3D hierarchical nanostructure significantly boosts the in situ generation of high-valence active species, which results in efficient and stable OER and UOR performances, and the synergistic merit of doping-induced facile reaction kinetics. Because of the structural benefits of a large surface area, charge-transfer promotion, good structural stability, and bifunctionality, a 1% La-doped α-Ni(OH)2 hierarchical nanostructure gives superior OER and UOR performances with low overpotentials, large catalytic current densities, and excellent operational stability. It is therefore a promising catalyst for use in simultaneous alkaline wastewater treatment and hydrogen production.

title: Bi-functional particles for integrated thermo-chemical processes: Catalysis and beyond

description: Particulate materials possessing dual functionalities have received tremendous investigations in many fields, owing to their superiority over mono-functional counterparts and their potential for process integration and intensification. This review focuses on bi-functional catalytic particles which also serve as sorbents/adsorbents or heat suppliers in the scheme of various thermo-chemical processes, enabling inherent separation or energy conservation within single-step operation. Bi-functional particles applied for integration of reaction and separation including sorption-enhanced hydrogen production and integrated capture and catalytic conversion processes are reviewed in detail, providing insights into material design and key performance indicators. On the other hand, bi-functional particles applied for integration of reaction and non-thermal radiation heating, including electrothermal and photothermal assisted heterogeneously catalyzed reactions, are also reviewed, with emphasis on the material property and energy efficiency improvement. These bi-functional particles show broad adaptability and feasibility in various reactions operated in integrated and intensified schemes, affording huge potentials for further improving productivity and efficiency in thermo-chemical processes.

title: Facile one-pot emulsion/sol-gel method for preparing wrinkled silica microspheres
title: Facile one-pot emulsion/sol-gel method for preparing wrinkled silica microspheres

description: The present manuscript describes a facile and versatile method for preparing uniform wrinkled silica microspheres with diameters of tens of microns. The method comprises a one-pot emulsion/sol-gel method using silica precursors of organosilane and tetraethoxysilane. By controlling the sol-to-gel transition of the silica precursors, a series of silica microspheres based on uniform emulsion droplets was synthesized by membrane emulsification. The silica microspheres had a variety of surface morphologies ranging from smooth, maze-like wrinkles to polygon-like ravines. It was possible to alter the surface morphologies of the microspheres by controlling the amount of organosilane in the dispersed phase and the amount of ammonia catalyst in the continuous phase of the emulsion. The grooves on the wrinkled microspheres were able to trap polymer nanoparticles of matching size, thereby demonstrating the potential usefulness of the microspheres in separation science and drug delivery.
