Oscillatory Catalytic Oxidation of Carbon Monoxide on a Schottky-Diode

Abstract

By a careful adjustment of the partial pressures in a mixture of carbon monoxide and oxygen, a gas composition can be realized which gives stoichiometric coadsorption of both species on platinum films. Under such conditions the reaction proceeds explosively and oscillations are observed. The nature of the adsorbed phase is deduced from the electrical properties of a Schottky diode.
