The temperature-programmed reduction with hydrogen was used to identify the phase composition of the active component and to study redox properties of MnOx-containing honeycomb monolithic catalysts prepared by two different methods: 1) “solution combustion synthesis” (SCS) on monolith surface; and 2) Co-extrusion of MnOx powder with oxide components of the monolith. It is assumed that both monolithic catalysts contain predominantly MnO and some amount of MnO2/Mn2O3. Among the studied catalysts, the monolithic catalyst obtained by the SCS method has the maximum activation energy of the second stage of the reduction of MnO2/Mn2O3, which consists in the reduction of Mn3O4 to MnO. This explains its high activity in the oxidation of methane.
