Summary: The synthesis of fine chemicals through the hydrogenation of nitroarenes to aromatic amines using H-2 under solvent-free conditions is crucial. In this study, ordered mesoporous carbon (OMC)-supported highly dispersed Ru nanoparticles (Ru NPs) were successfully prepared using a coordination-assisted solvent evaporation induced co-assembly method. The Ru/OMC composites showed high activity and selectivity for the hydrogenation of nitroarenes under solvent-free conditions. The strong metal-support interaction stabilized the Ru NPs and resulted in good recyclability and high selectivity.

Summary: Chemoselective hydrogenation of halogenated nitroarenes was achieved using a sulfur-doped ordered mesoporous carbon material anchored with ultrafine platinum clusters. The confinement effect of ordered pores and the strong metal-support interaction effectively controlled the aggregation and electronic states of the platinum clusters, leading to high selectivity and catalytic stability in the hydrogenation reaction. This study contributes to the development of noble metal-based catalysts for chemoselective hydrogenation reactions in green and sustainable chemical processes.

Summary: This study explores the optimization of Cu2O/CuO heterostructures for enhancing their (photo)catalytic performance. By evaluating catalysts with different Cu2O/CuO molar ratios, the researchers found that a ratio of 0.15 resulted in significantly higher reaction rate constants under blue LED light compared to lower (0.01) or higher (0.42) ratios. The photocatalyst also demonstrated good stability (>70% after 5 cycles) and excellent chemoselectivity in the selective reduction of the nitro group in the presence of other functionalities, such as -COOH, -CONH2, and -OH.

Summary: Size-controlled Pd nanoparticles were successfully synthesized in the pores of mesoporous silica nanoparticles, showing higher catalytic activity in the Suzuki-Miyaura cross-coupling and hydrogenation reactions compared to larger nanoparticles. The enhanced activity can be attributed to the increased number of coordinatively unsaturated sites and higher back donation capacity of the smaller nanoparticles.

Summary: A new and rapid synthetic route for N-doped ordered mesoporous carbon structure was reported by preferential heating of iron oxide nanoparticles by microwaves. The well-defined cubic mesoporous carbon structure showed remarkable improvement in hydrogen desorption kinetics as a host scaffold for NaAlH4, attributed to their ordered pore structure and N-doping effect.

Summary: Activated carbon (AC) is a low-cost porous material with high conductivity and a specific surface area. Waste-derived activated carbons (WDACs) have replaced commercially available AC due to their renewable, cost-effective, and eco-friendly characteristics. By embedding metal-organic frameworks (MOFs) in the WDAC matrix, a composite electrode is synthesized for energy storage applications. The composite electrode, which combines zinc-based zeolitic imidazole framework (ZIF-8) with waste paper-derived activated carbon (PAC-800), exhibits significantly enhanced electrochemical performance compared to pristine materials.

Summary: In this study, ruthenium-nickel bimetallic nanoparticles embedded in nitrogen-doped carbon mesoporous spheres (RuNi@ N-CMS) were prepared and used as a novel catalyst. The as-synthesized RuNi@ N-CMS nanostructure exhibited superior catalytic activity compared to Ni@ N-CMS and Ru@ NCMS nanostructures due to the synergistic effects of ruthenium-nickel. The catalyst showed promising potential in the hydrogenation of p-nitrophenol and reduction of nitroarene derivatives.

Summary: Conventional ordered mesoporous carbon (OMC) production requires long processing times, but this work demonstrates accelerated synthesis of OMCs using dielectric barrier discharge plasma, achieving carbonization within 15 minutes. The use of plasma enables faster production rates and does not require additional substrates within the OMC precursor systems.
