Abstract

The properties of a cobalt-modified nanoporous alumina formed by two-stage oxidation were investigated by electrochemical impedance spectroscopy. States corresponding to the different distribution of cobalt in the pores are considered. Equivalent circuits were selected that adequately correspond to the obtained impedance spectra, allowing the results of surface modification and its change to be evaluated in the study.

用频率阻抗谱研究钴改性纳米多孔氧化铝的性能

摘要

通过电化学阻抗谱研究了由两步氧化形成的钴改性纳米多孔氧化铝的性能。考虑对应于孔隙中钴不同分布的状态。选择与获得的阻抗谱充分对应的等效电路，从而可以在研究中评估表面改性及其变化的结果。
