Abstract

Here, the clever design of forming an ohmic contact between SnS₂ and MXene can regulate interfacial electron transport through Ti–O–Sn chemical bonds. This fast directional charge transport kinetics is attributed to the built-in electric field formed by the ohmic contact. As expected, the photoreduction CO₂ activity of the optimized SSTC-5 catalyst is 10.4 times that of the original SnS₂.
