Abstract
Methanol oxidation on a smooth polycrystalline platinum electrode is studied by dynamic electrochemical impedance spectroscopy at elevated temperatures employing an autoclave setup. By utilizing custom written software, impedance spectra for all applied electrode potentials are calculated. By increasing the temperature and/or sweep rate, it is shown that the region with three adsorbed species disappears, which is interpreted as less contribution of the parallel pathway at higher temperatures.
