摘要：

By using the Fourier transform (FT) technique, it is possible to perform electrochemical impedance spectroscopy in real time during the occurrence of DC voltage controlled surface reactions. The data obtained in this approach, a series of Nyquist plots as functions of DC control variables, can provide a wealth of time resolved information about Surface kinetics. We discuss in detail the theoretical and experimental considerations for such time resolved experiments. We focus primarily on the constraints and criteria of measurements in the context of new data acquisition electronics that became available during the last few years. We also present sample experimental results for a gold electrode. (C) 2004 Elsevier Ltd. All rights reserved.
