| Abstract: | Co nano-particles were prepared by microemulsion process. XRD and TEM measurements indicated that the average diameter of Co particles was 15 nm and particle size distribution was uniform. Cyclic voltammetry, chronoamperometry and EIS were used to test the performance of Co as electrocatalyst. It was indicated that the Co nano-particles exhibited a significant catalytic activity for electrochemical oxidation of ethanol in alkaline medium at room temperature. |
