Summary: The design and fabrication of Pt nanoparticle-decorated mesoporous ZnO-ZnS heterostructures were described and used effectively for photocatalytic CO2 conversion to yield CH3OH. The significantly enhanced reduction of CO2 was attributed to the synergistic effects of the ZnO-ZnS heterostructure and the incorporation of Pt NPs. The synthesized photocatalyst provides a new transfer route through which carriers can migrate to the outer surface as well as pore channels of the mesoporous ZnO-ZnS, thereby significantly minimizing the transfer distance for carriers and inhibiting photoinduced electron-hole recombination.

Summary: Photocatalytic CO2 reduction into chemical fuels is a promising strategy for CO2 conversion and solar energy utilization, but conversion efficiency remains a challenge. In this study, Ag-ion-doped CuV2O6 nanowires with abundant oxygen vacancies were prepared and used as catalysts for CO2 photoreduction. The Ag-doped CuV2O6 nanowires exhibited enhanced visible-light absorption ability, abundant oxygen vacancies, and high separation/transfer efficiency of electron-hole pairs, resulting in excellent photocatalytic performance for CO2 reduction. The optimized Ag-doped CuV2O6 nanowires showed a significantly enhanced CO evolution rate under visible-light irradiation compared to pure CuV2O6 nanowires. This work provides a valid strategy for improving visible-light photocatalytic CO2 reduction using CuV2O6 nanowires.

Summary: In this study, the photocatalytic abilities of Fe ions doped ceria with different morphologies for gaseous acetaldehyde degradation were compared. The results showed that Fe/CeO2-r nanorods exhibited 4.72 times higher photooxidation ability for acetaldehyde removal compared to pure CeO2-r nanorods. The analysis revealed that Fe/CeO2-r and CeO2-r mainly exposed {110} and {100} facets, while CeO2 and Fe/CeO2 with cube morphology mainly exposed {100} facets. The study also confirmed that Fe/CeO2 {110} is more conducive to acetaldehyde absorption and carbon dioxide desorption, and the doping of Fe ions improves the photocatalytic efficiency of ceria-based photocatalysts.

Summary: Tb-ZnO/reduced graphene oxide (Tb-ZnO/RGO) nanocomposites were synthesized by a simple one-step solvothermal method. The photocatalytic activity of the nanocomposites towards different pollutants was evaluated, showing enhanced activity due to improved charge separation and migration facilitated by Tb3+ and RGO. The smaller band gap, larger specific surface area, and efficient separation and transport of photo-generated carriers contribute to the enhanced photocatalytic activity.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
