Morpho-structural properties of CeO2 and (CeO2-CaO, CeO2-ZnO) Binary Nanostructured Oxides Prepared by the Electrodeposition Method

Ceria thin films (CeO2) were prepared by electrochemical cathodic deposition process. Different types of substrates were used such as aluminum, titanium and stainless steel. As it is possible to deposit separately pure ceria (CeO2), pure calcium oxide (CaO) and pure Zinc oxide (ZnO), CeO2-CaO and CeO2-ZnO binary oxides thin films were successfully obtained in one electrochemical condition set. By varying the current density, deposition time and electrolyte concentration, the amount of the electrodeposited material could be controlled. The deposits were studied by X-ray diffraction (XRD) and scanning electron microscopy ? SEM ? coupled to energy dispersive spectrometry ? EDS ?
