Abstract

The voltammetric behaviour of various platinized platinum electrodes in an H2SO4 (0.5 mol dm-3) supporting electrolyte was studied in order to investigate the effect of the platinization technique on the shape of the voltammetric curves. A wide variety of voltammetric behaviours was found depending on the platinization conditions in the case of the galvanostatic deposition method. Similarity to the results obtained by fast repetitive potential perturbation of smooth electrodes is demonstrated.
