Photoelectrochemical reduction of CO2 catalyzed by a 3D core–shell NiMoO4@ZnO heterojunction with bicentre at the (111) plane and thermal electron assistance

The new mechanism of PEC reduction of CO 2 on the bicentric catalyst is proven by DFT calculations and verified by the operando FTIR spectra, in which, the important intermediate of *OCH 2 could connect each other for C2 products.
