摘要
The BN/WO3 hybrid materials were synthesized by the calcined method and characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), UV-vis diffuse reflectance spectroscopy (DRS), Fourier transform infrared spectra (FT-IR). The photocatalytic activity of BN/WO3 hybrid materials was evaluated using Rhodamine B (RhB) as the target organic pollutant. The research results showed that the composites exhibited higher photocatalytic activity than the pure WO3, and a small amount of BN was beneficial for photogenerated electron and hole separation, which could enhance the photoactivity of BN/WO3. Based on the experimental results, a possible visible-light photocatalytic degradation mechanism was also proposed and discussed. (C) 2015 Elsevier B.V. All rights reserved.
