Two-dimensional metal phosphorus trisulfide nanosheet with solar hydrogen-evolving activity

Large-scale ultrathin nickel phosphorus trisulfide (NiPS3) hexagonal nanosheets are successfully synthesized through chemical vapor deposition (CVD) method in this work. The lateral size of the NiPS3 nanosheet, as thin as 3.5 nm, is larger than 15 µm. Notably, these NiPS3 nanosheets demonstrate high crystal quality and intriguing solar-driven water splitting photocatalysis in pure water.336
