Silver deposited on graphitic carbon nitride prepared under microwave irradiation for photodegradation of 2-chlorophenol

2-chlorophenol (2-CP) has been extensively utilized in various industries such as agricultural, cosmetic, paper, and biocide. The 2-CP has become a dangerous pollutant that can cause serious water pollution. Photocatalytic degradation is one of the effective destructive methods to remove 2-CP pollutant. Silver deposited on graphitic carbon nitride (Ag/g-C3N4) was prepared using the solid-state method without using any solvent and treated under microwave irradiation. The photocatalysts were characterized using UV-Vis DRS, N2 adsorption-desorption, FTIR, and FESEM analyses. The result shows that the bandgap energy was drastically narrowed after introducing Ag on g-C3N4. The deposited Ag on g-C3N4 provided a high performance (80%) of 2-CP after irradiation for 240 min under visible light. The enhancement of photodegradation was significantly influenced by the well dispersion of the Ag on the surface g-C3N4 and the low bandgap energy induced the synergistic effect between g-C3N4 and Ag. The existence of Ag metal on g-C3N4 prepared under microwave markedly can enhance a great potential photocatalyst for organic pollutants wastewater treatment.Copyright (c) 2022 Elsevier Ltd.
