Size-Controlled Cu 2 O Nanocubes by Pulse Electrodeposition

Abstract

In this work, highly uniform size-controlled Cu2O nanocubes can be successfully formed by means of pulse electrodeposition. The size distribution, crystal structure, and chem. state of deposited Cu2O nanocubes are characterized using SEM, transmission electron microscopy, X-ray diffraction and XPS. The phase transition from Cu2O to Cu can be controlled by const. current electrodeposition as a function of deposition time. In particular, the size of the Cu2O nanocubes can be controlled using pulse electrodeposition as a function of applied c.d. on SciFinder(R)
