Selective CO2-to-CO photoreduction over an orthophosphate semiconductor via the direct Z-scheme heterojunction of Ag3PO4 quantum dots decorated on SnS2 nanosheets

A direct Z-scheme heterojunction via decorating Ag 3 PO 4 quantum dots on SnS 2 nanosheets results in highly selective and efficient solar-driven CO 2 -to-CO photoreduction.
