摘　　要：本研究采用溶剂热法,利用金属钇的氧化物(Y_(2)O_(3))对Ti_(3)C_(2) Mxene进行掺杂改性制备Y_(2)O_(3)-Ti_(3)C_(2)复合光催化剂,用于紫外光下光催化水产氢研究。利用XRD,SEM,UV-Vis,FT-IR等手段对复合材料的晶体结构,微观形貌,光响应情况进行了表征分析。结果表明Y_(2)O_(3)的负载有效地抑制光生电子-空穴对的复合,从而进一步促进光解水反应的进行,使得体系的产氢效率得到了很大的提升,平均产氢速率可达389.24μmol·h^(-1)·m^(-3)·g^(-1),是原始Ti_(3)C_(2)材料(235.50μmol·h^(-1)·m^(-3)·g^(-1))的1.65倍。这为Ti_(3)C_(2)材料的改性提供了一种新思路。In this study,the Y_(2)O_(3)-Ti_(3)C_(2) composite photocatalysts were prepared by doping modification of Ti_(3)C_(2) Mxene with yttrium metal oxide(Y_(2)O_(3))via solvothermal method for photocatalytic hydrogen production under UV light.The crystal structure,microscopic morphology,and photoresponse of the composites were characterized and analyzed used XRD,SEM,UV-vis,and FT-IR,respectively.The results shown that the loading of Y_(2)O_(3) effectively inhibits the photogenerated electron-hole pair complexation,which further promotes the photolytic water reaction,and the hydrogen production efficiency of the system was greatly improved.The average hydrogen production rate was up to 389.24μmol·h^(-1)·m^(-3)·g^(-1),which was 1.65 times higher than that of the original Ti_(3)C_(2) material(235.50μmol·h^(-1)·m^(-3)·g^(-1))1.65 times.This provides a new idea for the modification of Ti_(3)C_(2) materials.
