Enhanced photoactivity on Ag/Ag3PO4 composites by plasmonic effect

► Ag/Ag3PO4 composites with different molar ratios have been prepared. ► The photoactivity is strongly dependent on the wavelength of the incident light. ► The photoactivity is dependent on the molar ratio of Ag/Ag3PO4 as well. ► Simulation results suggest a good agreement with our experimental observations.
