The g-C3N4/TiO2 nano-heterojunction is synthesized via the continuous hydrothermal deposition and reduction processes. The formation of heterojunction significantly reduced the recombination of generated charges, which was analyzed by time-resolved photoluminescence (TRPL). The as-prepared g-C3N4/TiO2 composites exhibited a great enhancement in photocatalytic hydrogen generation which can be attributed to the built-in electric field. This work gives a way to highly improve solar water splitting. |
