Photocatalytic Water Splitting Over a Protonated Layered Perovskite Tantalate H1.81Sr0.81Bi0.19Ta2O7



H1.81Sr0.81Bi0.19Ta2O7 was synthesized by treatment of Bi2SrTa2O9 with 3 M hydrochloric acid for 96 h. The formation rate of H2 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 H2 and O2 with the rates of 2.46 and 1.11 mmol h−1 g−1, respectively.
