The photocatalytic technology as a kind of green and potential technology has been paid more and more attention in ever-increasing environmental pollution and energy shortage. In this study, a practical strategy is proposed to facilitate effectively the separation of photogenerated electrons and holes by addition of graphene oxide in Ag3PO4 and Bi2WO6 nanocrystals semiconductor composites. Compared with GO-single component, the three-component RGO-Ag3PO4/Bi2WO6 composites exhibited improved photocatalytic activity with a degradation rate that reached up to 91% for tetracycline (TC) by visible light irradiation. Graphene oxide served as an electronic conduction medium to effectively transfer the photogenerated electrons from the conduction band of Bi2WO6 to the valence band of Ag3PO4; the all-solid-state Z-Scheme photocatalytic mechanism was proposed. Our work provides an effective method for development of pragmatic photocatalysts in the present environmental pollution, energy problems and other related fields.
