Original Paper


β- and α-phase porous Bi2O3 microspheres with an average size of around 4 μm had been synthesized by thermal treatment of Bi2O2CO3 microspheres at 350 and 400–500 °C respectively in an air atmosphere. The Bi2O2CO3 microspheres had been synthesized at a temperature of 180 °C by a hydrothermal process using Bi(NO3)3 as the bismuth source with the assist of citric acid. By combining the results of X-ray powder diffraction, transmission electron microscope, scanning electron microscopy, and UV–Visible absorption spectra, the structural, morphological and optical properties characterization of the products were performed. The photocatalytic activity of the as-prepared α- and β-phase porous Bi2O3 microspheres have been tested by degradation of methylene orange under visible light, indicating that porous β-Bi2O3 microspheres showed enhanced photocatalytic performance compared to P25 and α-Bi2O3 microspheres.
