Based on the metal-organic framework material (MOFs), the photocatalytic CO2 reduction is carried out in the gas phase medium, and committed to the controllable synthesis of high-efficient MOFs derivatives.

By studying the effects of the metal nodes and organic ligands of MOFs on their photocatalytic CO2 reduction activity, and regulating the corresponding mechanism, CO2 catalytic selectivity and activity was greatly enhanced and higher compared to that of other   similar materials.
