Abstract:
The objective of this investigation was to synthesize the graphite oxide-Ag3PO4(Ag3PO4-GO)composite and study its degradation properties of rhodamine(RhB). Therefore,a series of visible-light-driven GO-Ag3PO4catalysts with different GO contents,mainly including Ag3PO4-GO(0.5%),Ag3PO4-GO(1%),Ag3PO4-GO(1.5%)and Ag3PO4-GO(2%),was successfully synthesized and applied for degradation of RhB. The results showed that the band gap was approximately 2.39 eV,which was not affected by the addition of GO. Furthermore,the catalyst,Ag3PO4-GO(1%),showed the best photocatalytic activity with a pH range from 5 to 7. Additionally,the degradation rates correlated negatively with the initial concentrations of RhB. Ag+on the GO surfaces might capture photoelectron e-,which would favor Ag3PO4 to separate e- and h+ under visible light irradiation,and significantly enhanced the photocatalytic activity and stability.
