Hydrothermal Synthesis and Photo-catalytic Property of Bi25FeO40 Powders

摘要：

Bi25FeO40 powders have successfully been synthesized by simple hydrothermal method. The effect of the concentration of mineralizer and stoichiometry on the prepared samples was investigated. With the UV-Vis spectra, Bi25FeO40 powders have a broad absorption band in the range of 400-600 nm and a good visible-light-response ability. Photo-catalytic activity of Bi25FeO40 powders was evaluated by the degradation of methyl violet solution under UV-Vis light irradiation, which is found that Bi25FeO40 is efficient for photo-degradation of the methyl violet due to its own crystal structure.
