Abstract:

Photocatalytic technology is a promising strategy for hydrogen peroxide (H?O?) synthesis. However, the synthesis efficiency of H?O? still needs improvement due to the limited quantum efficiency, light absorption capability, and high cost of photocatalytic materials. To address these issues, in this study, we designed and synthesized indium (In)-doped porous carbon nitride (In-g-C?N?) photocatalytic materials and investigated their photocatalytic performance for direct H?O? synthesis under visible light irradiation. The results showed that the optimized In-g-C?N? exhibited a photocatalytic H?O? generation rate of 450.28 μmol/(g·h), which is 3.12 times higher than that of undoped carbon nitride (g-C?N?). Combined with experimental characterization and data analysis, it was revealed that the introduction of indium effectively promoted the separation efficiency of photogenerated charge carriers. By introducing templates to modulate the micro-nano structure of the material, the photocatalytic performance for H?O? production was significantly enhanced.
