Bi2W2O9、Bi2WO6 和 Bi3TiNbO9 由钙钛矿板与 Bi2O2 层交错的层状结构组成，对从甲醇水溶液中析出 H-2 和从硝酸银水溶液中析出 O-2 表现出光催化活性。具有Aurivilius结构和2.8 eV带隙的Bi2WO6在可见光照射（λ>420 nm）下对O-2析出反应具有活性。
Bi2W2O9, Bi2WO6, and Bi3TiNbO9 consisting of layered structure with perovskite slabs interleaved with Bi2O2 layers showed photocatalytic activities for H-2 evolution from an aqueous methanol solution and O-2 evolution from an aqueous silver nitrate solution. Bi2WO6 with the Aurivillius structure and a 2.8 eV band gap was active for the O-2 evolution reaction under visible light irradiation (lambda>420 nm).
