Abstract:The graphite-phase nitrided carbon g-C3N4 was stripped by modified concentrated sulfuric acid stripping method to obtain highly dispersed flake g-C3N4.And Ag/g-C3N4 composite catalyst was prepared by solid-phase synthesis method.The prepared materials were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM).The photocatalytic properties of massive g-C3N4, flaked g-C3N4 and Ag/g-C3N4 composite were tested on the photodegradation of methylene blue (MB).The results show that the flaked g-C3N4 has better dispersibility in the aqueous solution than the massive g-C3N4, and the photocatalytic activity is improved obviously.The prepared Ag/g-C3N4 composite catalyst has the best catalytic performance, and can rapidly catalyze the rapid conversion of p-nitrophenol to p-nitroaniline.
