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, due to intrinsic inertness (~750 kJ mol-1 of C=O bond dissociation energy) of linear CO2 molecule.Here, in an attempt to establish a universal guideline for rational design of stable photo-catalyst with high photo-conversion efficiency and selectivity for CO2 conversion. We systematically investigate the structure-photocatalytic properties correlations using binary CdS colloidal nanocrystal (NC) as a model system. The colloidal CdS nanocrystal is chosen not only for the tunable band structure (≥2.41 eV) which can potentially afford visible light harvesting and sufficient energetic e- and h+, but also for the versatile controllability over its morphology, crystal structure and surface termination, which provides a broad monitoring window enable us to clarify the structure-property relationship in complex CO2 photo-reduction process. |
