Abstract
The photocatalytic technology provides a simple and effective strategy for the ever-increasing environmental and energy problem. In this work, we put forward a practical method to facilitate effectively the separation of photogenerated electrons and holes by addition of graphene oxide in Ag3PO4and Bi2O3nanocrystals semiconductor composite. Compared with GO-single component, the three-component GO-Ag3PO4/Bi2O3composites with the optimum Ag3PO4/Bi2O3ratio (6:4) and content of GO (6 wt-%) presented a further improvement on the photodegradation of tetracycline by visible light irradiation driven. GO served as a medium is used to effectively transfer of the photogenerated electrons from the conduction band Bi2O3of to the valence band of Ag3PO4, the Z-Scheme photocatalytic degradation mechanism was proposed. Our work provides an effective method for development of pragmatic photocatalyst in present environmental pollution, energy problems and other related fields.
