摘要：

Bi2WO6-coated carbon (BI2WO6@C) microspheres were prepared by a two-step hydrothermal method using glucose as a carbon source The physicochemical properties of the prepared microspheres were characterized by X-ray diffraction (XRD) field emission scanning electron microscopy (FESEM) Brunauer-Emmett-Teller (BET) and UV/Vis diffuse reflectance spectrum (DRS) The photocatalytic activity of the as-prepared sample was determined by degradation of gas-phase benzene under visible-light irradiation and was compared to N doped TiO2 It was revealed that the photocatalytic performance of the Bi2WO6 was enhanced greatly by the doping of carbon microspheres The photocatalytic conversion rate and mineralization rate of benzene over the Bi2WO6@C microspheres were 42 6% and 80 0% respectively which were much higher than that of N-doped TiO2 (C) 2010 Elsevier BV All rights reserved
