Facile synthesis of small Ag@AgCl nanoparticles via a vapor diffusion strategy and their highly efficient visible-light-driven photocatalytic performance

Abstract

Uniform and small Ag@AgCl nanoparticles were for the first time prepared through a vapor diffusion strategy at room temperature. The size of the Ag@AgCl nanoparticles could be controlled by a diffuse vapor of HCl molecules with a slow rate and PVP used as a precursor. The smallest Ag@AgCl NPs exhibit excellent photocatalytic activity and stability.
