Preparation of Y2O3-Ti3C2 Photocatalyst and Hydrogen Production Properties
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.
