Using red phosphorus as precursors, P/BiPO4composites were synthesised successfully via a facile hydrothermal method by the reaction between amorphous red (P) and Bi(NO3)3aqueous solution without any additive. The phases structures, morphologies and optical properties of the obtained samples were studied by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectra (FTIR), Scanning electron microscopy (SEM), Energydispersive X-ray (EDX), UV-Vis DRS and photoluminescence spectroscopy (PL). The P/BiPO4composite photocatalyst displayed much higher photocatalytic performance for a typical dye pollutant methylene blue (MB) degradation than the BiPO4synthesised by a typical method under simulated visible light (λ>400 nm) and exhibited more enhanced catalytic efficiency than BiPO4synthesised by a typical method. The excellent performance can be attributed to the high separation capacity of photogenerated electron-hole pairs and demonstrated to be a promising photocatalytic material.
