Summary: The development of difunctional photocatalyst for hydrogen production and high value-added fine chemicals is of great industrial significance. The CdS(ZB)/CdS(WZ)/Ni-BTC composites show excellent catalytic activity in photocatalytic selective oxidation of benzyl alcohol to benzaldehyde coupled with hydrogen evolution reaction, achieving high conversion and yield rates. The results demonstrate that a significant portion of H2 and D2 in the reaction system originate from the benzyl alcohol and D2O, respectively.

Summary: The development of a free-standing Ni-Al2O3 ensemble derived from NiAl-layered double hydroxides (NiAl-LDHs) grown onto a Ni-foam has proven to be effective in achieving a unique combination of high activity/selectivity and enhanced heat/mass transfer. The catalyst derived from un-calcined NiAl-LDH/Ni-foam exhibits a high turnover frequency and the capability to convert a high percentage of acetone into isopropanol with almost 100% selectivity.

Summary: In this study, different-sized Ni nanoparticles supported on nitrogen-doped carbon were synthesized by controlling the pyrolysis temperature. The electrooxidation of benzyl alcohol over these nanocatalysts showed varying performance, which was attributed to the difference in adsorption strength of reactant molecules.

Summary: This study presents a new method for the synthesis of CuMnOx catalysts using a half carbonized citrus grandis peel assisted hard template method. The shift of the oxide pairs from CuO-Cu1.4Mn1.6O4 to Mn2O3- Cu1.4Mn1.6O4 has been achieved by tuning the Cu/Mn molar ratio, resulting in high selectivity and efficiency in the oxidation of benzyl alcohol using H2O2 as oxidant. The interaction between the Cu1.4Mn1.6O4 constituent and Mn2O3 constituent enhances the formation of Cu+ species, leading to a Fenton-like catalytic oxidation process.

Summary: By depositing Ni-Ni(OH)2 and/or NiPi nanocrystals co-catalysts on the surface of TiO2 nanotube arrays, the PEC performance was significantly enhanced with higher photocurrent and hydrogen evolution rate. The ternary TNTAs/Ni-Ni(OH)2/NiPi structure combines the advantages of different co-catalysts, successfully separating photogenerated electron-hole pairs.

Summary: In this study, a green approach to produce benzyl phenyl sulfide derivatives using thioanisoles and benzyl alcohols as starting materials and the ionic liquid 1-propylsulfonate-3-methylimidazolium trifluoromethanesulfonate as the catalyst was reported. The mechanism was found to involve the activation of the starting materials by the synergistic effect of the cation and anion of the ionic liquid, leading to the formation of benzyl phenyl sulfide derivatives. This method offers a simple, efficient, and environmentally friendly way to synthesize benzyl phenyl sulfide derivatives with promising application potentials.

Summary: This study reports a highly selective and stable Ni-C-Al2O3 catalyst for the hydrogenation of biomass-derived furfuryl alcohol to tetrahydrofurfuryl alcohol. The catalyst is prepared through in-situ growth of Ni-based metal organic frameworks (Ni-BTC) on Al2O3 followed by thermal decomposition. The results show that the catalyst's structure and performance are closely related, with small metal Ni particle size and appropriate interaction between Ni and the support being key factors for high furfuryl alcohol conversion and tetrahydrofurfuryl alcohol selectivity.

Summary: In this study, a highly active and selective NiCx/Ni-foam catalyst is reported, which is obtained by the endogenous growth of NiC2O4 onto a Ni-foam and subsequent H2-reduction treatment. The preferred catalyst with high content of NiCx is capable of converting 63.6% or 94.3% CO at 350 degrees C or 400 degrees C with trace or < 0.8% CH4 formation for a feed gas with H2O/CO/Ar molar ratio of 4/1/9, and is stable for at least 110 h. It is experimentally and theoretically revealed that the Ni3C facilitates the dissociative activation of H2O and favors CO to form carboxylate species (favorable for CO2 formation) rather than active Ni(CO)n intermediates for CH4 formation thereby enabling the catalyst with high WGSR activity and selectivity.

Summary: In this study, sub-30 nm nanocomposites of CuO/ZnO/NiO were engineered using Dodonaea viscosa leaf extract. The growth of the nanocomposites was investigated by varying precursor concentrations and surfactants. The as-prepared composites showed CuO (monoclinic), ZnO (hexagonal primitive), and NiO (cubic) phases with an average size of 29 nm. The nanocomposites exhibited antimicrobial and antioxidant activities, with higher antioxidant potential than ascorbic acid.
