铟掺杂多孔氮化碳用于高效可见光驱动过氧化氢合成
Indium-Doped Porous Carbon Nitride for Efficient Visible-Light-Driven Hydrogen Peroxide Synthesis
摘要
Abstract
Photocatalytic technology is a promising strategy for hydrogen peroxide(H₂O₂)synthesis.However,the synthesis efficiency of H₂O₂ 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-C₃N₄)photocatalytic materials and investigated their photocatalytic performance for direct H₂O₂ synthesis under visible light irradiation.The results showed that the optimized In-g-C₃N₄ exhibited a photocatalytic H₂O₂ generation rate of 450.28 μmol/(g·h),which is 3.12 times higher than that of undoped carbon nitride(g-C₃N₄).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 H₂O₂ production was significantly enhanced.关键词
