The morphology, size, crystal structure and composition of the products were investigated by XRD, SEM, TEM, XPS, and UV–vis instruments. It was found the reaction time and the amount of Ag nanowires play crucial roles in the formation of well-defined 1D Ag@Cu<sub>2</sub>O core–shell heteronanowires. The resultant 1D Ag@Cu<sub>2</sub>O NWs exhibit much higher photocatalytic activity toward degradation of organic contaminants than Ag@Cu<sub>2</sub>O core–shell nanoparticles or pure Cu<sub>2</sub>O nanospheres under solar light irradiation. The drastic enhancement in photocatalytic activity could be attributed to the surface plasmon resonance and the electron sink effect of the Ag NW cores, and the unique 1D core–shell nanostructure.
