Abstract：A facile co-precipitation method followed by thermal treatment was used to prepare Bi2O3.The morphology,structure and photocatalytic activity of Bi2O3 were characterized by field-emission scanning electron microscopy,X-ray diffraction spectroscopy,UV-Vis absorption spectrophotometer and fluorescence spectrophotometer,respectively.The morphology and photocatalytic activity of Bi2O3 are relevant to the calcination temperature.Bi2O3 treated at 400 ℃ shows the best photocatalytic activity in the degradation of methyl orange (86％).The excellent photocatalytic activity should be attributed to its good light adsorption and low recombination of photo-induced charge carries.
