Abstract: Using SnCl 2 and tetrabutyl titanate as precursors, a series of Sn doped TiO 2 photocatalysts with
2+
different Sn doping content were prepared by one-step hydrothermal method. The structure and spectral
characteristics of the samples were characterized by XRD, UV-Vis, SEM, EDX, XPS and BET. 300 W
Xenon lamp was used as light source to investigate the photocatalytic activity of different samples under
4+
full wave band and visible light. The results revealed that Sn doped TiO 2 could not produce hydrogen in
2+
visible light, while Sn doped TiO 2 could. The sample with a Ti/Sn molar ratio of 20 demonstrated the best
photocatalytic activity for hydrogen production, and the efficiency of hydrogen production in full wave
band and visible light were 50.3 and 33 μmol/(h·g), respectively. Moreover, the catalyst still showed a stable
efficiency of hydrogen production even after being five cycles.
