Thermocatalytic Behavior of Manganese (IV) Oxide as Nanoporous Material on the Dissociation of a Gas Mixture Containing Hydrogen Peroxide

In this article, we present an overview on the thermocatalytic reaction of hydrogen peroxide (H [Formula: see text] O [Formula: see text]) gas on a manganese (IV) oxide (MnO [Formula: see text]) catalytic structure. The principle of operation and manufacturing techniques are introduced for a calorimetric H [Formula: see text] O [Formula: see text] gas sensor based on porous MnO [Formula: see text]. Results from surface analyses by X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM) of the catalytic material provide indication of the H [Formula: see text] O [Formula: see text] dissociation reaction schemes. The correlation between theory and the experiments is documented in numerical models of the catalytic reaction. The aim of the numerical models is to provide further information on the reaction kinetics and performance enhancement of the porous MnO [Formula: see text] catalyst.
