Using Frequency Impedance Spectroscopy to Study the Properties of Cobalt-Modified Nanoporous Alumina

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...

Description
Summary: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.
