On the way to prepare stable platinum electrodes for the characterization of the Hupd reaction by electrochemical impedance measurements, a novel, feather-like platinum surface modification was found and characterized. In addition, a precursor morphology was identified. Electrochemical impedance measurements at selected potentials in the Hupd potential region yield information on double layer capacity, adsorption capacity, and adsorption resistance of the Hupd reaction for these two electrode morphologies.
