Preparation of chemically modified electrodes by attachment of platinum carbonyl clusters, and their efficient electrocatalytic action in anodic oxidation of methanol

Abstract

Chemically modified electrodes, prepared by impregnating surface-modified graphite discs and anion-exchange membranes with [Pt₃(CO)₆]_n^2–(n= 3 or 5; platinum carbonyl cluster anions) by an ion-exchange technique, provide higher specific electrocatalytic activities for the anodic oxidation of methanol than conventional platinum electrodes.
