Abstract
Recently lead-free halide perovskite have shown great performances, especially in solar cell applications. On the other hand, graphitic carbon nitride g-C 3N 4 materials have been rising interest thanks to the tunable electronic structure and excellent physicochemical stability, which could serve as an excellent candidate for photocatalytic applications. In our research, we tried to overcome the low charge transportation efficiency and chemical instability anchoring a cesium/bismuth-based perovskite on g-C 3N 4 nanosheets to prepare composite photocatalyst based on nitrogen-iodine chemical bonding. Among different lead-free halide perovskite loads, the CNCSBI001 composite (g-C 3N 4:Cs 3Bi 2I 9 10:0.1 w%) showed the better stability and an outstanding yield for photocatalytic degradation of organic compound in water solution under visible light irradiation. Hydrogen evolution test were also perform to test the activity of the synthesized compound under simulated solar light irradiation. The former study aim to provide insights on the use of halide perovskite-based Z-scheme photocatalyst for different photocatalytic applications.
