摘要
Plasmonic photocatalyst Ag@AgCl, in which Ag nanoparticles are deposited on the surfaces of AgCl particles (SEM image depicted), was prepared by treating Ag2MoO4 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. (Figure Presented) © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
