A catalyst for the deep oxidation of organic compounds and carbon monoxide contains 2.7-11.5 mass. % of manganese (with respect to elementary manganese), balance alumina. Manganese stays as non-stoichiometric manganese oxide beta -Mn3O4+x, where 0.1</=x</=0.25, containing 80-95% of all manganese atoms, and as manganese aluminate containing 20-5% of manganese atoms. Alumina in the active component is presented by the high temperature forms alpha -Al2O3 (72-95 catalyst mass. %) and ( delta + theta )-Al3O3 (28-05 catalyst mass. %). The catalyst active component has a monolith defect structure, particles size being 50-70 ANGSTROM . Catalyst phase composition and structure form during its thermal treatment at 900 DEG -1000 DEG C.
