Pureα-Bi2O3with nanoneedle array structure was synthesized directly by hydrothermal method. The optic absorption of theα-Bi2O3paricles was cut off at ~483 nm and the band gap of theα-Bi2O3was estimated to be 2.57 eV. The photocatalytic activity of theα-Bi2O3samples was higher than TiO2under a visible light irradiation. As a conclusion, relative narrow band gap ofα-Bi2O3nanoneedle array compared to anatase and the special morphology of nanoneedle array structures may improve the photocatalytic activity in visible light irradiation.
