One-Pot Hydrothermal Synthesis of g-C3N4/BiPO4 Nanocomposites with Significant Photocatalytic Activity

Abstract

The g-C3N4/BiPO4 composites have been successfully synthesized via a one-pot hydrothermal process, which can be used to degrade the organic dyes (rhodamine B and methylene blue) under simulated sunlight irradiation. X-ray diffraction (XRD), scanning electron microscope (SEM), UV-Vis diffuse reflectance spectra and Fourier transform infrared (FTIR) spectroscopy have been employed to characterize the samples. The g-C3N4/BiPO4 composites exhibited higher photocatalytic activity than pure BiPO4. And the optimum photocatalyst shows the outstanding photocatalytic activity, which exhibited 99.0% and 86.6% decolorization rate of RhB and MB, respectively.
