Abstract
- Photocatalytic CO<subscript>2</subscript> reduction utilizing solar energy is a clean, environment-friendly strategy converting CO<subscript>2</subscript> into hydrocarbon fuels to solve the energy crisis and climate issues. Herein, we report the synthesis of Cu-doped SnS<subscript>2</subscript> nanosheets via a simple hydrothermal method. The prepared Cu-doped SnS<subscript>2</subscript> composite displays superior photocatalytic CO<subscript>2</subscript> reduction activity. The optimized CH<subscript>3</subscript>OH yield of the composite is two times higher than that of pure SnS<subscript>2</subscript>. The enhanced photocatalytic performance is attributed to effective charge separation resulting from the thinner nanosheets and delocalization of electrons from SnS<subscript>2</subscript> to Cu, high visible light utilization efficiency, enlarged S<subscript>BET</subscript>, negative shift of the flat-band potential and reduced charge transfer resistance with the introduction of Cu atoms. This work suggests the potential application of Cu-doped SnS<subscript>2</subscript> in photocatalytic CO<subscript>2</subscript> reduction. [ABSTRACT FROM AUTHOR]
