In situ anion-exchange synthesis and photocatalytic activity of Ag8W4O16/AgCl-nanoparticle core-shell nanorods

▶ Ag8W4O16/AgCl-nanoparticle core-shell nanorods were prepared. ▶ The AgCl nanoparticles with a diameter of less than 30 nm were obtained. ▶ AgCl-nanoparticle shell can be easily controlled by NaCl solution. ▶ AgCl nanoparticles exhibited high photocatalytic activity.
