Graphene-wrapped Ag3PO4/LaCO3OH heterostructures for water purification under visible light

We demonstrate synthesis of Ag3PO4/LaCO3OH/GR heterojunction photocatalyst by in-situ wet chemical method. This photocatalyst exhibited enhanced photocatalytic activity which was ascribed to the constructive effect derived from the co-catalytic effect of LCO, resulting in accelerated charge separation, and the presence of GR effectively prevents decomposition of Ag3PO4 into metallic Ag (photocorrosion), offering better stability for reusability.198
