Abstract

We report on a novel yet facile approach to the mass production of photocatalytic Ag₃PO₄ particles by using graphene oxide (GO) sheets as templates. GO was first stabilized with poly(diallyldimethylammonium chloride), a poly-cationic electrolyte, Ag₃PO₄ crystals of submicro-size were then synthesized over the GO sheets by using Ag(NH₃)₂⁺ and H₂PO₄⁻ as the starting materials via precipitation reactions. After a desirable UV irradiation treatment, Ag₃PO₄ was partially reduced to Ag⁰ and GO to graphene; tetrahedral crystals consisted of Ag, Ag₃PO₄ and graphene were obtained. The Ag/Ag₃PO₄/graphene combinational nanostructures are highly transparent and moreover, showing high visible-light-driven photocatalytic activities. Photodegradation studies with acridine orange (AO) as the targeted chemicals gave better results than TiO₂ (P25), WO₃, and the sole Ag/Ag₃PO₄, demonstrating the high applicability of the Ag/Ag₃PO₄/graphene combinational photocatalyst.
