摘要：
The voltammetric behaviour of platinized electrodes in relation to their formation potential was studied (deposition from H2PtCl6 solution). It was found that the ratio of the heights of the two most characteristic hydrogen peaks appearing on the voltammograms obtained in 0.5 mol dm(-3) H2SO4 depends on the potential of the formation of the electrode exhibiting one or two singularities, depending on the composition of the platinizing solution. It is shown that within a certain range of parameters a preselected pattern in the voltammetric behaviour of platinized electrodes with high real surface area (roughness factor values up to 600-800) can be realized by choosing an appropriate condition for the platinization.
