Characterization and Visible-Light Photocatalytic Activity of Nano-Bi2MoO6 Catalysts Prepared by Hydrothermal Process
The Nano-Bi2MoO6 was prepared using Bi(NO3)3•5H2O and Na2MoO4•2H2O as starting materials by a hydrothermal process. The prepared Bi2MoO6 product was characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM) and UV-visible diffuse reflectance spectroscopy (DRS). It was found that the prepared nano-Bi2MoO6 show narrow band gap of 2.88 eV. Consequently, the prepared nano-Bi2MoO6 show high visible-light photocatalytic activity for decomposition of Rhodamine B in comparison with the commercial Degussa P25, which was ascribed to the visible-light absorption.
