Thermal Oxidation Mechanism of CuO Nanowires and Layered Copper Oxides Structure

Abstract:

A layered structure of different copper oxides was produced by thermal oxidation of copper. The structure and microstructure of the different layers were investigated by scanning electron microscopy and transmission electron microscopy. From the substrate to the free surface, three different layers are formed, namely, Cu₂O layer, CuO layer and CuO nanowires. Based on our observations, a possible formation mechanism of layered copper oxides and CuO nanowires was proposed. The results shed light on the oxidation process of metals and provide insight into the synthesis of copper oxides and CuO nanowires.
