| Abstract: | Cerium dioxide ultrafine powders were prepared by electrochemical method using composite coating of Ru, Ir and Rh as anode, and Cerium (Ⅲ)nitrate and ammonium nitrate as electrolyte.The powders were analyzed by using XRD and TEM.It shows that the CeO2 powers were cubic in structure and CeO2 particles were basically spherical in shape, and the sizes of the particles were smaller than 30 nm.The polarization of the composite coating anode was better than Pt anode, and both its voltage and energy consumption were lower than Pt anode.Several factors that affected current efficiency, such as concentration of solution, current density, pH value, were analyzed. |
