Paper Title:
Photocatalytic Properties of α-Bi2O3 Nanoneedle Array Synthesized by Hydrothermal Method
  Abstract

Pure α-Bi2O3 with nanoneedle array structure was synthesized directly by hydrothermal method. The optic absorption of the α-Bi2O3 paricles was cut off at ~483 nm and the band gap of the α-Bi2O3 was estimated to be 2.57 eV. The photocatalytic activity of the α-Bi2O3 samples was higher than TiO2 under a visible light irradiation. As a conclusion, relative narrow band gap of α-Bi2O3 nanoneedle array compared to anatase and the special morphology of nanoneedle array structures may improve the photocatalytic activity in visible light irradiation.
