Photocatalytic dye degradation and hydrogen production activity of Ag_3PO_4/g-C_3N_4 nanocatalyst

摘要

Recently, photocatalysts have received increasing attention owing to their potential to resolve issues regarding the environment and alternative sources of energy. Here, highly effective visible-light-driven organic-inorganic hybrid heterojunction graphitic carbon nitride-silver phosphate nanocomposite (GCN-Ag3PO4 NCs) were synthesized via the hydrothermal method. The synthesized photocatalyst was characterized by X-ray diffraction, Fourier transform infrared, X-ray photoelectron spectroscopy, and UV-Vis diffuse reflectance spectroscopies, scanning electron microscopy and transmission electron microscopy, and subsequently utilized for photocatalytic dye degradation and hydrogen production. The GCN-Ag3PO4 NCs exhibit excellent photocatalytic activity for methylene blue degradation under solar simulator visible light, with a hydrogen production activity higher than that of pristine Ag3PO4. The hydrogen production rate of GCN-Ag3PO4 NCs is 44.5 times higher than that of Ag3PO4. Therefore, GCN-Ag3PO4 NCs are promising as effective photocatalysts for environmental protection.
