To further improve the light response range and photocatalytic activity of Bi2SiO5, the Bi2SiO5/BiOBr type-II heterojunction photocatalysts were constructed by in-situ partial ion exchange strategy using Bi2SiO5 as precursor. The crystal phases, morphologies, chemical compositions, optical properties and textural structures of as-synthesized Bi2SiO5/BiOBr photocatalysts were characterized by the corresponding analytical techniques. The photocatalytic activities of samples were evaluated by degrading Rhodamine B (RhB) solution under visible ligh...
