Abstract
- Photocatalytic reduction of CO<subscript>2</subscript> to valuable chemicals is one of the important solutions to the problems of global warming and energy shortage. Here, a Bi<subscript>2</subscript>S<subscript>3</subscript>/CdIn<subscript>2</subscript>S<subscript>4</subscript> S-scheme heterojunction was constructed by a simple solvothermal method, which greatly facilitated the segregation and migration of photogenerated charge carriers. The optimized heterojunction achieved an efficient methyl formate (MF) generation rate (5464 μmol h<superscript>−1</superscript> g<superscript>−1</superscript>) in the photocatalytic CO<subscript>2</subscript>/methanol reduction system, which was about 29-fold that of pure Bi<subscript>2</subscript>S<subscript>3</subscript>. The preliminary mechanism of the photocatalytic system over the S-scheme Bi<subscript>2</subscript>S<subscript>3</subscript>/CdIn<subscript>2</subscript>S<subscript>4</subscript> heterojunction was proposed using in situ technology and experimental comparison. This work provides insights into the application of metal sulfide heterojunctions in the field of MF research and the photocatalytic CO<subscript>2</subscript>/methanol reduction system.
