▎ 摘 要
The composite photocatalysts composed of BiPbO2Cl and reduced graphene oxide (rGO) were synthesized by a one-step hydrothermal method. The UV-vis absorbance spectra results show that the BiPbO2Cl nanosheet absorbs more visible light when it is combined with graphene. The Raman spectra results indicate that the D and G bands are not visible from the Raman spectra of BiPbO2Cl, and the peak strength of two bands is increased with the increase of graphene content. The obtained 2 wt% rGO/BiPbO2Cl nanosheet composites exhibit higher photocatalytic activity, which is 5.7 times compared with that of BiPbO2Cl nanosheets. The improved photocatalytic activity of the rGO/BiPbO2Cl composites is ascribed to effective charge transfer due to graphene. (C) 2016 Elsevier B.V. All rights reserved.
