VO4‐Modified Layered Double Hydroxides Nanosheets for Highly Selective Photocatalytic CO2 Reduction to C1 Products

The conversion of CO2 into high‐value added chemicals driven by solar energy is an effective way to solve environmental problems, which is, however, largely restricted by the competition reaction of the hydrogen evolution reaction (HER) and easy electron–hole recombination, etc. Herein, VO4‐supporte...

Description
Summary:The conversion of CO2 into high‐value added chemicals driven by solar energy is an effective way to solve environmental problems, which is, however, largely restricted by the competition reaction of the hydrogen evolution reaction (HER) and easy electron–hole recombination, etc. Herein, VO4‐supported ultrathin NiMgV‐layered double hydroxide (V/NiMgV‐LDH) nanosheets are successfully fabricated, and the extended X‐ray absorption fine structure (EXAFS) and density function theory (DFT) calculations reveal that VO4 species are located on the top of V atoms in the NiMgV‐LDH laminate. The V/NiMgV‐LDH is proved to be highly efficient for the photocatalytic CO2 reduction reaction (CO2PR) with high selectivity of 99% for C1 products and nearly no HER (
