Rationally designed Ti3C2 MXene@TiO2/CuInS2 Schottky/S-scheme integrated heterojunction for enhanced photocatalytic hydrogen evolution

The development of novel and efficient heterojunction photocatalysts is still a challenging issue for achieving highly efficient solar-to-chemical energy conversion. Herein, we report the construction of Ti3C2 MXene@TiO2/CuInS2 (M@T/CIS) integrated Schottky/step-scheme (S-scheme) heterojunction by two-step hydrothermal process for boosting photocatalytic hydrogen generation activity. The as-prepared M@T/CIS hybrid photocatalysts exhibit the...
