Electrode properties of ruthenium oxide nanosheet ultra-thin films for electrochemical capacitors

Abstract

Electrode properties of ruthenium oxide nanosheet films composed of 1 oxide layer were investigated by cyclic voltammetry tests. Nanosheet ultra-thin films were prepared by Langmuir¬¬–Blodgett method. Cyclic voltammograms of nanosheet ultra-thin films showed very sharp and symmetrical redox peaks which were not observed for bulk materials. Nanosheet ultra-thin films enabled to observe electrochemical behavior of the very surface of electrode and obtain a better understanding of the intrinsic electrochemical properties.
