Efficient plasmonic photocatalytic activity on silver-nanoparticle-decorated AgVO3 nanoribbons

Abstract

An Ag/AgVO₃ plasmonic photocatalyst was synthesized via in situ reduction of AgVO₃ by NaBH₄ at room temperature. The Ag/AgVO₃ showed high photocatalytic activity due to the relatively high conductivity and electron-storing capacity of Ag nanoparticles, which facilitate the charge transfer between AgVO₃ and Ag nanoparticles. FDTD simulation indicates that the formed Ag nanoparticles induce SPR leading to the increased electric field and the enhanced absorption of visible light.
