Abstract
Abstract Graphitic carbon nitride (g-C 3 N 4 ) with high photocatalytic activity toward degradation of 4-nitrophenol under visible light irradiation was prepared by HCl etching followed by ammonia neutralization. The structure, morphology, surface area, and photocatalytic properties of the prepared samples were studied. After treatment, the size of the g-C 3 N 4 decreased from several micrometers to several hundred nanometers, and the specific area of the g-C 3 N 4 increased from 11.5 m 2 /g to 115 m 2 /g. Meanwhile, the photocatalytic activity of g-C 3 N 4 was significantly improved after treatment toward degradation of 4-nitrophenol under visible light irradiation. The degradation rate constant of the small particle g-C 3 N 4 is 5.7 times of that of bulk g-C 3 N 4 , which makes it a promising visible light photocatalyst for future applications for water treatment and environmental remediation.
