Preparation of Ag3PO4/GO/Bi2MoO6 Composite Material and Efficient Eegradation of Xanthate in Tailings Wastewater
Ag3PO4/GO/Bi2MoO6 ternary composite material was synthesized using a two-step hydrothermal method.By controlling the amount of GO and Ag3PO4 precursor added,a series of Ag3PO4/GO/Bi2MoO6 composite materials with different loading ratios were prepared,and their photocatalytic performance was evaluated with ethyl xanthate as the target degradation product.Simultaneously,FT-IR,SEMand UV-vis methods were used to characterize the microstructure and optical properties of the composite material.The results showed that compared with Bi2MoO6 and GO/Bi2MoO6,the photocatalytic activity of Ag3PO4/GO/Bi2MoO6 composite material was significantly improved when the GO addition was 5 mg;When the amount of Ag3PO4 precursor added was 8 mmol,its photocatalytic rate was about 7.6 times that of GO/Bi2MoO6 and 34.0 times that of Bi2MoO6.In addition,under the same experimental conditions,the degradation rate of Ag3PO4/GO/Bi2MoO6 composite material remained stable after 5 cycles of recycling.
