摘要
本研究采用溶剂热法,利用金属钇的氧化物(Y2O3)对Ti3C2 Mxene 进行掺杂改性制备Y2O3-Ti3C2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Y2O3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389.24 μmol·h-1·m-3·g-1,是原始Ti3C2材料(235.50 μmol·h-1·m-3·g-1)的1.65 倍.这为Ti3C2材料的改性提供了一种新思路.
Abstract
In this study,the Y2O3-Ti3C2 composite photocatalysts were prepared by doping modification of Ti3C2 Mxene with yttrium metal oxide(Y2O3)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 Y2O3 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 389.24 μmol·h-1·m-3·g-1,which was 1.65 times higher than that of the original Ti3C2 material(235.50 μmol·h-1·m-3·g-1)1.65 times.This provides a new idea for the modification of Ti3C2 materials.
