Plasmonic photocatalyst Ag@AgCl, in which Ag nanoparticles are deposited on the surfaces of AgCl particles (SEM image depicted), was prepared by treating Ag 2 MoO 4 with HCl to form AgCl powder and then reducing some Ag + ions in the surface region of the AgCl particles to Ag 0 . This photocatalyst is highly efficient, for example in the degradation of organic dyes, and stable under visible light.
