Solar-driven carbon dioxide (CO2) photo-reduction into chemical fuels provides a sustainable way to produce renewable energy sources by consuming the ever-increasing greenhouse gas. Nevertheless, the intrinsic imbalanced mobility of hole (h+) and electron (e-) coupled with mismatch between the desired migration of e- (and h+) and randomly distributed reduction reaction sites (and oxidation reaction sites) would increase the chance for e--h+ recombination and photo-corrosion, thus, hindering the photoconversion efficiency and the long-term stability of the photo-catalyst. Here, in an attempt to establish a universal guideline for rational design of stable photo-catalyst with high photoconversion efficiency and selectivity for CO2 conversion. We systematically investigate the structure-photocatalytic properties correlations using binary CdS colloidal nanocrystal (NC) as a model system.
