摘要

In this paper,we report our attempts to raise the efficiency of liquid reduction method when using high specific surface area TiO2 (HSTiO2) by doping Au.Characterization of Au-HSTiO2 was conducted via XRD,UV-vis,SEM,and photocurrent intensity.The experimental results show that Au-HSTiO2 exhibits prominently higher photocatalytic hydrogen production than TiO2 and HSTiO2.Enhanced photosynthetic hydrogen production ability of Au-HSTiO2 should be attributed to the presence of abundant surface active sites of HSTiO2,remarkably extending electronic holes in Au doping.This study provides a promising photosynthetic material for hydrogen production.
