Synthesis of copper oxides films via anodic oxidation of copper foil followed by thermal reduction

Copper oxides films were successfully synthesized via anodic oxidation of copper foil at various conditions followed by thermal reduction of oxidized samples in inert nitrogen atmosphere. The morphology and phase composition of final and intermediate products were determined by scanning electron microscopy, X-ray diffraction and Raman spectroscopy techniques. Optimal synthetic conditions of Cu2O films on copper foil surface were established.
