Abstract

The metastable γ-Bi₂O₃ photocatalysts with different morphologies were fabricated by means of a chemical precipitation method. The microstructure of as-prepared samples was characterized by X-ray diffraction, transmission electron microscopy and ultraviolet-visible diffusion reflectance spectroscopy. The photocatalytic performance of Bi₂O₃ powder was evaluated using rhodamine B as a model pollutant under visible light irradiation. The visible light photocatalytic activity of Bi₂O₃ with different morphologies is as follows, nanorod>nanorod/nanoflake>N doped TiO₂>irregular particle>agglomerated particle. The γ-Bi₂O₃ shows the best photocatalytic performance and it can effectively degrade 97% RhB within 60min.
