Summary: This study investigates the conversion of CO2 into high-value added chemicals driven by solar energy. The results show that the use of VO4-supported ultrathin NiMgV-layered double hydroxide as a catalyst achieves high efficiency and selectivity for the photocatalytic CO2 reduction reaction under visible light. The excellent performance of V/NiMgV-LDH can be attributed to its modulation of the band structure, promotion of electron-hole separation, and strong bonding with CO* and H* to facilitate hydrogenation and inhibit the formation of by-product H-2.

Summary: Photocatalysis has the potential to reduce CO2 greenhouse gases. Layered double hydroxides (LDHs) are promising photocatalysts with good catalytic activity, low synthesis cost, and large-scale preparation. This study focused on the effects of different divalent metal species on CO selectivity in aluminum-based LDHs and found that ZnAl-LDH exhibited better CO selectivity and CO yield compared to MgAl-LDH and NiAl-LDH. These findings provide a feasible strategy to improve the selectivity of CO photocatalytic reduction of CO2 by regulating divalent metal species in aluminum-based LDHs.
