Abstract
Abstract Molecular oxygen reduction studies in acid medium have been performed with cluster materials of the Chevrel phase type supported on carbon paste electrodes. It was found that the metal intercalated in the channels between Mo 6 clusters enhances their catalytic activity. This is explained by the formation, during oxygen reduction, of peroxo intermediates bonded both to the transition metal cluster and to the intercalated atom. The advantage of the resulting bimetallic catalysis is even more pronounced using mixed clusters. The increasing activity of differently intercalated cluster materials can be correlated with their structural parameters.
