Preparation and Photocatalytic Activity of g-C3N4/BiPO4 Photocatalyst

BiPO4 was synthesized using Bi(NO3)(3)center dot 5H(2)O and Na3PO4 center dot 12H(2)O as starting materials, and then hybridized with g-C3N4 to enhance the performance of g-C3N4/BiPO4. The g-C3N4/BiPO4 photocatalysts were characterized by XRD, FT-IR, SEM, TEM and BET. The photocatalytic activities were evaluated by the degradation of methylene blue under the visible light in the photocatalytic reaction device. The results show that the visible light photocatalytic activity of BiPO4 is greatly enhanced by the hybridization of g-C3N4. When the loading amount of g-C3N4 is 7% of BiPO4, the photocatalytic activity of the composite photocatalyst is optimal under the visible light irradiation.
