In this work, a facile one-step hydrothermal route was demonstrated for the fabrication of Cu/Cu2O composite nanowires. Metallic Cu nanoparticles were formed via in-situ reduction on the surface of Cu2O nanowires. The investigation of scanning electron microscopy and transmission electron microscopy revealed that well-defined Cu/Cu2O composite nanowires, with diameters around 60 nm and lengths of about several microns, were formed at 100 degrees C in the presence of PVP with glucose as a reductant. Moreover, Cu nanoparticles, with diameters less than 30 nm, were highly dispersed and strongly a...
