Visible Light Photocatalytic Properties of Metastable gamma-Bi2O3 with Different Morphologies. Hao, W., Gao, Y., Jing, X., Zou, W., Chen, Y., & Wang, T. Journal of Materials Science & Technology, 30(2):192–196, February, 2014. WOS:000330579000016

The metastable gamma-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 \textgreater nanorod/nanoflake \textgreater N doped TiO2 \textgreater irregular particle \textgreater agglomerated particle. The gamma-Bi2O3 shows the best photocatalytic performance and it can effectively degrade 97% RhB within 60 min.
