Descripción
The application of square-wave potential treatments to platinum electrodes in acid solution under suitable conditions produces remarkable changes in both the roughness and crystallographic orientation of the electrode surface. The influence of the symmetry of the perturbing potential at different frequencies on the growth mode of the platinum overlayers has been studied. The overall effect is discussed in terms of the relative contribution of metal electrodissolution/electrodeposition and oxide layer electroformation/electroreduction processes.
