Abstract:

Cu2O micro- and nanoparticles with different morphologies(cube, microsphere, hollow sphere and core-shell) were prepared by polyol method, using copper nitrate, copper acetate, and copper acetylacetonate as raw materials. The samples were characterized by X-ray diffraction(XRD), field emission scanning electron microscopy(FE-SEM), transmission electron microscopy(TEM), high resolution TEM(HRTEM) and ultraviolet-visible(UV-Vis) spectroscopy. We investigated the influences of copper sources, reaction time, the polyol types and other conditions on the morphology of cuprous oxide. The mechanism for the formation of Cu2O in polyol process is discussed. Synthesis of cuprous oxide micro- and nanostructures with different shape can be controlled by the simple and inexpensive polyol method. This method is promising for the preparation of oxides with controlled morphologies.

Key words: cuprous oxide, polyol method, shape control
