Inhibition of CO oxidation over Cu-Mn-Ce-O composite catalyst in the presence of dry powder fire extinguishing agent: Mechanism investigation and mitigation strategy

A review of catalytic oxidation of carbon monoxide over different catalysts with an emphasis on hopcalite catalysts

“…The mechanisms responsible for conduction in copper manganite is phonon assisted electron jumping between Mn 3+ and Mn 4+ cations occupying octahedral sites. 115 The rate as far as reduction is concerned between Mn 3+ and Cu 2+ , i.e., based on the improvement in the fractions of Mn 2+ and Cu + , relies on at the synthesis conditions based on these temperatures. The Cu + ion goes into tetrahedral areas.…”
