A selection of graphitic materials of both scientific as well as commercial importance has been modified by deposition of various metals at very low coverages under overpotential or underpotential conditions. Nanoparticles were found with some metals. The changes in the -electrocatalytic activity of the supporting electrode by the metal modification were studied using electrochemical impedance measurements of a fast redox system. The carbon/solution interface was characterized with surface Raman spectroscopy, electrochemical impedance measurements and cyclic voltammetry.
