Summary: Ketones play a crucial role in pharmaceuticals, food additives, and organic synthesis. Efficient and environmentally friendly selective oxidation cleavage of olefins is important for ketone synthesis. This study utilized a bismuth-rich Bi4O5Br2 photocatalyst, obtained through a microwave method, as a heterogeneous catalyst under visible-light irradiation. By using water/dioxane as the solvent and molecular oxygen as the oxygen source, various ketones were obtained in moderate to good yields. The catalyst exhibited stable activity over four cycles and the oxidative cleavage of C=C double bonds was attributed to superoxide radicals or photogenerated electrons and holes.

Summary: 5,8-dicyanopicene, a visible-light-absorbing picene derivative, was synthesized and its photocatalytic activity for hydrogen production via water decomposition was evaluated. A CN-picene thin-film deposited on a quartz substrate showed increased hydrogen formation activity with film thickness. The uneven deposition of CN-picene on the substrate resulted in increased surface roughness and higher water-decomposition activities for catalysts with thicker films.

Summary: This study investigated the alkylation performance of X zeolites with different particle sizes in a continuous-flow slurry reactor. The results showed that larger particle size can enhance catalyst stability, while smaller particle size is favorable for product diffusion. However, significant dealumination and structural defects can occur in smaller particles, impacting their acidity and overall alkylation performance. Thus, an optimal particle size range is speculated for the use of X zeolites in a slurry reactor for alkylation.

Summary: A series of CHR-VOx were prepared by controllable hydrogen treatment and reduced to states dominated by V5+ and V4+ species. The catalytic roles of V-species and O-species for cyclohexane oxidation were explored. The surface properties of CHR-VOx underwent remarkable changes, leading to significant improvement in catalytic performance. XPS and Raman confirmed the reduction behavior. Moderate-reduced CHR-VOx with 78.7% multi-liganded-oxygen (O-L) showed the best conversion for cyclohexane (11.8%), while over-reduced CHR-VOx with a large content of V4+ species (33%) exhibited the best selectivity for adipic acid (44.3%). O-L sites were identified as the active sites for cyclohexane activation, while V4+ species were regarded as oxygen vacancies (OVs) contributing to further oxidation to adipic acid.

Summary: Pt/C and SO42-/ZrO2 were used as catalysts for the synthesis of p-aminophenol through the catalytic transfer hydrogenation of nitrobenzene in water with formic acid as the hydrogen source. The optimal Pt loading for PAP selectivity was found to be 1 wt%. The presence of different valence states of Pt affected both the nitrobenzene hydrogenation and formic acid decomposition. Among different solid acid catalysts tested, SO42-/ZrO2 exhibited the highest catalytic activity for p-aminophenol formation. Under the optimized reaction conditions, the conversion of nitrobenzene reached 80.0%, with a selectivity of 47.6% for p-aminophenol.

Summary: The mechanism of the reaction between CO2 and styrene oxide for cyclic carbonate was revealed using density functional theory calculations. The noncatalytic reaction occurred via a concerted mechanism, while in the presence of guanidine and tetrabutylammonium iodide (TBAI) co-catalysts, the epoxide ring-opening by nucleophilic attack of an iodide anion was predicted to be the rate-determining step. Guanidine acted as the H-bond donor to activate styrene oxide, facilitating the reaction with a lower activation barrier.

Summary: Copper nanorods (Cu-NRs) exhibit significant plasmonic behavior and can act as efficient catalysts in redox processes and coupling. A benign decarboxylative approach, utilizing localized surface plasmon resonance (LSPR) assisted catalysis with Cu-NRs, has been developed for the production of alkane analogues from alkyl carboxylic acids under visible light. The catalyst shows a broad substrate scope and high functional group tolerance, without the need for an external oxidant or proton source. A plausible mechanism for this recyclable nano-catalyst has also been proposed based on control experiments.
