Abstract：Ag/Ni-based Ag3PO4/CNTs composite films for sensors were prepared by electrochemical deposition on nickel matrix, and their photocatalytic activity and stability were tested under visible light. The results show that the composite membrane form a network structure composed of CNTs and Ag3PO4, and CNTs can play a good supporting role to the network structure and make the composite membrane obtain better stability. A characteristic peak of CNTs with high strength is formed in the composite film, and there is a strong interaction between CNTs and Ag3PO4. Compared with Ag3PO4 film, the composite film has better light absorption performance in the ultraviolet and visible regions, and effectively promotes the photocatalytic reaction. The composite membrane can be used continuously for 5 times under the condition of stable photocatalytic activity. Compared with the system without capture agent, the degradation rate of the system with tert-butanol decrease, and that with the addition of ethylenediamine tetra acetic acid decrease significantly.
