Changes In The Morphology Of Platinum Electrodeposition Induced By Fast Square Wave Potential Modulation

Faceting of platinum with preferred orientation can easily be produced by applying, during a certain time, a potential, cycling at a frequency greater than 0.5 kHz, to a polycrystalline electrode in acid solution within the potential range of the underpotential decomposition of water. By adequately...

description Faceting of platinum with preferred orientation can easily be produced by applying, during a certain time, a potential, cycling at a frequency greater than 0.5 kHz, to a polycrystalline electrode in acid solution within the potential range of the underpotential decomposition of water. By adequately changing the potential limits, the frequency and the duration of the periodic perturbation applied to the electrode, different platinum surfaces are produced whose voltammetric behaviour approaches that reported from initially single crystal platinum surfaces under definite perturbation conditions. Each type of faceted surface with preferred orientation exhibits well-defined forms in SEM microphotographs.
