Kinetic study of navy blue photocatalytic degradation over Ag3PO4/BiPO4@MIL-88B(Fe)@g-C3N4 core@shell nanocomposite under visible light irradiation

Abstract

Novel quaternary Ag3PO4/BiPO4@MIL-88B(Fe)@g-C3N4 (AB@MIL-88B(Fe)@g-CN) nanocomposite with core@shell structure was successfully fabricated by two simple steps. The prepared samples were characterized by various techniques. Photocatalytic activity of the prepared samples was evaluated by degradation of navy Acid Blue 92 (AB92) dye as an organic pollutant under visible light irradiation. Highly intensified photocatalytic efficiency was observed for quaternary AB@MIL-88B(Fe)@g-CN nanocomposite compared to the other samples. Experimental results exhibited that the photocatalytic activity enhancement can be mainly assigned to the strong visible light absorption and effective separation of photogenerated charge carriers by heterojunction formed between counterparts of AB@MIL-88B(Fe)@g-CN nanocomposite. The trapping experiments demonstrated that •OH and O2•− anion radical were the main reactive species in the degradation reaction in the presence of superior photocatalyst.
