Preparation of Ni foam supported Co electrode and its electrocatalytic performance for hydrazine electrooxidation

采用恒电位法制备泡沫镍负载钴(Co/Nifoam)电极。通过循环伏安法和计时电流法制得Co/Nifoam电极对肼电氧化反应的催化性能,结果表明,Co/Nifoam电极具有较高的催化肼电氧化活性。在1.0mol·L^-1NaOH+0.02mol·L^-1N2H4中,肼在Co/Nifoam上氧化的峰电流密度可达62.1mA·cm^-2。

The Ni foam supported Co(Co/Ni foam)electrode was prepared by a potentiostatic method.The electrocatalytic performance of the Co/Ni foam electrode for hydrazine electrooxidation was investigated by cyclic voltammetry and chronoamperometry.The results showed that the Co/Ni foam electrode exhibited the excellent electrocatalytic activity for hydrazine electrooxidation.An oxidation peak current density of 62.1 mA·cm^-2 was achieved in the solution containing 1.0 mol·L^-1 NaOH and 0.02 mol·L^-1 N 2H 4.
