Rapid fabrication of silver–cuprous oxide core–shell nanowires for visible light photocatalysts

Abstract

We report a new method that enables fabrication of Ag–Cu2O core–shell nanowires (NWs) by using pulsed ultraviolet laser light to irradiate a mixed aqueous copper acetate and Ag NW solution. Multiple experimental characterization techniques indicate that laser irradiation can induce both rapid (0.5–6 min) and controllable growth of Cu2O (20–150 nm) on the Ag NWs. Finite-difference time-domain simulations and mechanism analyses show that the good photocatalytic properties of the Ag–Cu2O core–shell NWs are related to the enhanced visible light absorption caused by localized surface plasmon resonance and the improved electron–hole separation efficiency caused by the Ag–Cu2O Schottky junction.
