In the present work, a generalization of some of the interpretations of heterogeneous catalysis to the case of oxide film electrocatalysts has been attempted, using conductive boron-doped diamond supports. The very high stability of this material allowed the study of the catalytic properties of noble-metal oxide modifications from the level of submonolayer to a few monolayers, avoiding the serious interference of the reactivity of the generally adopted metal supports.

Abstract
In the present work, a generalization of some of the interpretations of heterogeneous catalysis to the case of oxide film electrocatalysts has been attempted, using conductive boron-doped diamond supports. The very high stability of this material allowed the study of the catalytic properties of noble-metal oxide modifications from the level of submonolayer to a few monolayers, avoiding the serious interference of the reactivity of the generally adopted metal supports. A mechanism for the chlorine evolution reaction at submonolayers of oxide electrocatalyst has been proposed, basing on a chlorine radical spillover stage.File in questo prodotto:
