Summary: In this study, new Cu2O/Fe3O4 and Ti3C2/Cu2O/Fe3O4 ternary nanocomposites were fabricated and used as photocathodes in PEC-CO2R for the first time, achieving low overpotentials, high product selectivities, and high current densities. The successful junctions of Ti3C2/Cu2O/Fe3O4 were determined, confirming the efficient separation of photogenerated electrons and holes and the abundant photoinduced electrons supply to the CO2RR. The use of 2D MXenes with Cu2O/Fe3O4 ternary nanocomposites as catalysts for PEC-CO2R is a novel and efficient approach.

Summary: Rare giant and all-inorganic core-shell cobalt polyoxoniobates (Co-PONbs) with diverse shapes, nuclearities and topologies have been isolated. These Co-PONbs are the largest and contain the greatest number of Co ions and the largest cobalt clusters known thus far. They possess intriguing and atomically precise core-shell architectures and can serve as molecular models of the cubic-spinel Co3O4. Additionally, they show potential as promising cluster molecular catalysts for visible-light-driven CO2 reduction.

Summary: This study demonstrates an efficient photocatalytic reduction of Cr(VI) to Cr(III) under visible light using AgI/CeO2@gC3N4 nanocomposite, showing significantly higher photo-reduction efficiency compared to other binary nanocomposites. The optimized ternary photocatalyst achieved a 99.6% reduction efficiency for Cr(VI) within 75 minutes. The enhanced activity is attributed to effective electron/hole pairs separation and a hetero-junction structure.

Summary: In this study, high CH4 activity and selectivity in solar-light-driven CO2 reduction are achieved by integrating bifunctional Cu2O and Cu-MOF core-shell co-catalysts with semiconductor TiO2. The synergistic effect of Cu2O and Cu-MOF in the core-shell structure lowers the formation barrier of key intermediates, resulting in high CH4 yield, efficient electron transfer, and hydrocarbon selectivity. This work provides a strategy for designing efficient photocatalysts through precise regulation of components.
