An efficient visible-light-driven plasmonic photocatalyst with regard to graphene oxide(GO) hybridized Ag/Ag3PO4(Ag/Ag3PO4/GO) nanostructures has been facilely synthesized via a deposition-precipitation method.The synthesized nanostructures have been characterized by means of scanning electron microscopy(SEM),energy-dispersive X-ray spectroscopy(EDX),X-ray diffraction(XRD),UV-vis spectra,Fourier transform infrared spectra(FT-IR),X-ray photoelectron spectroscopy(XPS),and Raman spectra.It has been disclosed that compared with the bare Ag/Ag3PO4 nanospecies,the GO hybridized nanostructures display enhanced photocatalytic activity for the photodegradation of methyl orange pollutant under visible-light irradiation.It is suggested that the reinforced charge transfer and the suppressed recombination of electron-hole pairs in Ag/Ag3PO4 /GO,the smaller size of Ag/Ag3PO4 nanospecies in Ag/Ag3PO4/GO,all of which are the consequences of the hybridization of GO,are responsible for the enhanced photocatalytic performance.The investigation might open up new opportunities to obtain highly efficient Ag3PO4-based visible-light-driven plasmonic photocatalyst for the photodegradation of organic pollutants.
