化学的共沈法により作製したFe₃O₄電極の電気的還元処理と電気化学特性

抄録

Fe₃O₄ spinel ferrite nano-particles, promising electrode materials for redox capacitors, were prepared with chemical coprecipitation technique. In this research, the effects of electrical reduction on electrochemical properties of Fe₃O₄ spinel ferrite electrodes were studied. The results show that the pseudo-capacity of Fe₃O₄ electrodes was increased after the electrochemical reduction at -0.7V vs. Ag/AgCl reference electrode. Moreover, it was found that crystal structure of Fe₃O₄ electrodes remained almost unchanged even after the electrochemical reduction.
