Cuprous Oxide Nanowires Prepared by an Additive-Free Polyol Process

The polyol method was employed for the first time to synthesize cuprous oxide nanowires using only a precursor of Cu(II) acetate monohydrate and diethylene glycol(DEG). With careful control of the reaction temperature (190oC), the precursor concentration (0.01-0.1 mol/L) and the reaction time (6 h), we prepared Cu2O nanowires witha diameter of approximately 20 nm and a length up to 5 um. The nanowires were characterized by SEM, TEM, XRD and IR spectroscopy.
