Carbon-doped SnS(2) nanostructure as a high-efficiency solar fuel catalyst under visible light

Photocatalytic formation of hydrocarbons using solar energy via artificial photosynthesis is a highly desirable renewable-energy source for replacing conventional fossil fuels. Using an l-cysteine-based hydrothermal process, here we synthesize a carbon-doped SnS(2) (SnS(2)-C) metal dichalcogenide na...

description Photocatalytic formation of hydrocarbons using solar energy via artificial photosynthesis is a highly desirable renewable-energy source for replacing conventional fossil fuels. Using an l-cysteine-based hydrothermal process, here we synthesize a carbon-doped SnS(2) (SnS(2)-C) metal dichalcogenide nanostructure, which exhibits a highly active and selective photocatalytic conversion of CO(2) to hydrocarbons under visible-light. The interstitial carbon doping induced microstrain in the SnS(2) lattice, resulting in different photophysical properties as compared with undoped SnS(2). This SnS(2)-C photocatalyst significantly enhances the CO(2) reduction activity under visible light, attaining a photochemical quantum efficiency of above 0.7%. The SnS(2)-C photocatalyst represents an important contribution towards high quantum efficiency artificial photosynthesis based on gas phase photocatalytic CO(2) reduction under visible light, where the in situ carbon-doped SnS(2) nanostructure improves the stability and the light harvesting and charge separation efficiency, and significantly enhances the photocatalytic activity.
