Using an l-cysteine-based hydrothermal process, here we synthesize a carbon-doped SnS2 (SnS2-C) metal dichalcogenide nanostructure, which exhibits a highly active and selective photocatalytic conversion of CO2 to hydrocarbons under visible-light. The interstitial carbon doping induced microstrain in the SnS2 lattice, resulting in different photophysical properties as compared with undoped SnS2. This SnS2-C photocatalyst significantly enhances the CO2 reduction activity under visible light, attaining a photochemical quantum efficiency of above 0.7%. The SnS2-C photocatalyst represents an important contribution towards high quantum efficiency artificial photosynthesis based on gas phase photocatalytic CO2 reduction under visible light, where the in situ carbon-doped SnS2 nanostructure improves the stability and the light harvesting and charge separation efficiency, and significantly enhances the photocatalytic activity. © 2018 The Author(s).[SDGs]SDG7[SDGs]SDG13carbon; carbon dioxide; hydrocarbon; nanomaterial; sulfide; tin derivative; tin sulfide; unclassified drug; carbon dioxide; catalysis; catalyst; efficiency measurement; energy resource; fossil fuel; fuel cell; gas phase reaction; hydrocarbon; hydrothermal system; light intensity; nanoparticle; photochemistry; photolysis; photosynthesis; reduction; renewable resource; separation; solar power; adsorption; Article; chemical composition; crystal structure; density functional theory; desorption; diffuse reflectance spectroscopy; light; nanocatalyst; photocatalysis; photochemistry; photoluminescence; photosynthesis; quantum chemistry; Raman spectrometry; reduction (chemistry); scanning electron microscopy; solar energy; structure analysis; transmission electron microscopy; X ray diffraction; X ray photoelectron spectroscopyjournal article10.1038/s41467-017-02547-42-s2.0-85043493857https://www.scopus.com/inward/record.uri?eid=2-s2.0-85043493857&doi=10.1038%2fs41467-017-02547-4&partnerID=40&md5=3765233dff4ab3395d286468cc4f7fc0
