| Abstract: | In this paper, we report our attempts to raise the efficiency of liquid reduction method when using high specific surface area TiO_2(HSTiO_2) by doping Au. Characterization of Au-HSTiO_2 was conducted via XRD, UV-vis, SEM, and photocurrent intensity. The experimental results show that Au-HSTiO_2 exhibits prominently higher photocatalytic hydrogen production than TiO_2 and HSTiO_2. Enhanced photosynthetic hydrogen production ability of Au-HSTiO_2 should be attributed to the presence of abundant surface active sites of HSTiO_2, remarkably extending electronic holes in Au doping. This study provides a promising photosynthetic material for hydrogen production. |
