摘要:

光催化技术是一种具有潜力的过氧化氢(H2O2)合成策略。 然而,受限于光催化材料的量子效率、光吸收能力及高昂材料成本,H2O2的合成效率仍需提升。 为解决上述问题,本研究设计并合成了铟(In)掺杂的多孔氮化碳(In-g-C3N4)光催化材料,并探讨了其在可见光照射下直接合成H2O2的光催化性能。 结果显示,经过优化,所得In-g-C3N4的光催化生成H2O2速率为450.28 μmol/(g·h),相较未掺杂氮化碳(g-C3N4),活性提高了3.12倍。 结合实验表征与数据分析,揭示了In掺杂有效促进了材料中的光生载流子的分离效率; 同时,通过引入模板调控材料的微纳结构,显著提高了光催化合成H2O2的性能。

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.
