Abstract
Graphene-Ag3PO4 hybrid nanocomposite with the unique triangular morphology of Ag3PO4 is successfully fabricated by simple one pot hydrothermal method. The hybrid Graphene-Ag3PO4 nanocomposite photocatalyst was characterized by different advanced analytical instruments for morphological and physiochemical properties of material. The results are promising and nano Graphene-Ag3PO4 hybrid composite shows improved photocatalytic movement than pure Ag3PO4 for degradation of phenol. SEM shows the in-situ growth of finely distributed triangular shaped Ag3PO4 nanoparticles over the surface of graphene sheets. Production of .OH radicals on the Ag3PO4 surface was detected by the PL technique applying coumarin as an investigating chemical. The effect of graphene (from 10 to 50 wt %) loading in composite material on rates of degradation of phenol in aqueous solution was investigated. Among prepared catalysts an optimum 20 wt% graphene loading in hybrid nanocomposite visible light catalyst shown two times higher activity than pure Ag3PO4, further loading of graphene lowers activity.
