Abstract

The composite photocatalysts composed of BiPO4and reduced graphene oxide (rGO) were synthesized bya facile hydrothermal method. Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD),transmission electron spectroscopy (TEM), photoluminescence emission spectra (PL) and UV-vis diffusereflection spectroscopy (DRS) were used to characterize the titled composites. The results showed thatthe BiPO4particles can be immobilized on the surface of rGO sheets, and the crystallization phases ofBiPO4were significantly influenced by the amount of graphene. The phase transformation of BiPO4crystalfrom hexagonal to monoclinic phase was observed. The introduction of rGO improved the optical prop-erties of BiPO4and thereby enhancing the utilization of light. Compared with pure BiPO4under similarsynthesis condition, the BiPO4/rGO composites exhibit a much higher photodegradation activity, whichwas confirmed by photoluminescence (PL) spectra and photocurrent (PC) generation.
