Abstract: 
A new composite photocatalyst Ag/AgCl core–shell sphere was synthesized at room temperature by using a simple and generic approach. SEM images revealed that the as-prepared catalyst showed a uniform morphology with an average size of about 2 m. The photocatalytic activity was significantly dependent on the molar ratio of Ag⁰:Ag⁺ on the surface of the catalyst, the optimum ratio being 0.035. Recycling experiments confirmed the excellent stability ofthe catalysts, without any silver leaching fromthe surface ofthe catalyst, suggesting thatthe photocatalystAg/AgCl core–shell sphere was a form of active and stable visible-light driven plasmonic material.
