A novel
class of one-dimensional (1D) plasmonic Ag@Cu<sub>2</sub>O core–shell
heteronanowires have been synthesized at room temperature for photocatalysis
application. 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.
