Ag@AgI/Ni thin films plasmonic photocatalyst were prepared by electrochemical method.The surface morphology,phase structure,optical characteristics and band structure of the thin film were characterized by scanning electron microscopy(SEM),X-ray diffraction(XRD) and ultraviolet-visible diffuse reflectance spectroscopy(UV-Vis DRS),respectively.Its photocatalytic properties and stability were evaluated with rhodamine B(Rh B) as a model compound under the simulated solar irradiation.Using a method of adding ac...
