In situ growth of Ag2S quantum dots on SnS2 nanosheets with enhanced charge separation efficiency and CO2 reduction performance

SnS 2 /Ag 2 S nanohybrids are used in photo-driven CO 2 reduction with excellent CO/CH 4 -evolving activity. The advanced photoactivity is attributed to the charge separation efficiency through the electron bridge of the Sn–S–Ag bond via co-shared S atoms between SnS 2 and Ag 2 S.
