電気化学周波数変調AFMによる電気二重層界面のOperando局所解析

抄録

Electric double layer (EDL) is formed at the electrolyte / electrode interface and provides a field of energy storage or accumulated career conduction in addition to that of electrochemical reaction i.e. electron transfer with chemical bond rearrangement. Electrochemical frequency modulation AFM (EC-FM-AFM) enables acquisition of the liquid side information from the highly sensitive force spectrum vertical to the interface as well as the atomic scale resolution imaging of the solid side at the electrode surface, both are often affected by the electrode potential. In this article, some examples of “operando analyses” of such electrochemical interfaces by using EC-FM-AFM are introduced.
