Resumo

PLATINUM NOBLE METALS USING MODIFIED ELECTRODES.Nickel, palladium and platinum microcrystals were dispersed in films covering a vitreous carbon plate electrode by ion exchange followed by electroreduction of their ions.These modified electrodes were used in the electrocatalytic hydrogenation of several substrates of different classes and their efficiency is reported.A comparison among them was performed based on the structural characteristics of the metals.A modified electrode containing platinum showed to be more efficient than a palladium modified electrode and the one of nickel was the less efficient.
