摘要：

H1.81Sr0.81Bi0.19Ta2O7 was synthesized by treatment of Bi2SrTa2O9 with 3 M hydrochloric acid for 96 h. The formation rate of H-2 from CH3OH/H2O solution under UV light irradiation is 57.67 mmol h(-1)g(-1) for H1.81Sr0.81Bi0.19Ta2O7 without co-catalyst. It also showed high activity for decomposition of pure water into H-2 and O-2 with the rates of 2.46 and 1.11 mmol h(-1)g(-1), respectively.
