Abstract: The composite photocatalysts composed of BiPO4 and 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 BiPO4 particles can be immobilized on the surface of rGO sheets, and the crystallization phases of BiPO4 were significantly influenced by the amount of graphene. The phase transformation of BiPO4 crysta lfrom hexagonal to monoclinic phase was observed. The introduction of rGO improved the optical prop-erties of BiPO4 and thereby enhancing the utilization of light. Compared with pure BiPO4 under similarsynthesis condition, the BiPO4/rGO composites exhibit a much higher photodegradation activity, which was confirmed by photoluminescence (PL) spectra and photocurrent (PC) generation.
