Abstract

The electrocatalytic properties of palladium are of interest in connection with direct formic acid fuel cell development. Cyclic voltammograms recorded for activated palladium electrodes in sulphuric acid solution exhibit a quasi-reversible surface redox transition at ca. 0.25 V (RHE) and, in the presence of formic acid, the oxidation of the latter undergoes a dramatic change in rate at the same potential. Catalysis in this case evidently involves surface active site behaviour, low coverage protruding palladium species undergoing oxidation in a repetitive manner, the resulting surface cations coordinating bisulphate anions and acting as mediators for the formic acid oxidation reaction.
