Catalytic Properties of the Spinel-Like CuxMn3−xO4 Copper Manganese Oxides—An Overview

Copper manganese oxide spinels and related (multiphase) materials with the formula CuxMn3−xO4 are active catalysts in a wide variety of industrially important processes due to their great diversity phase relations, metal ion valence/site distribution, chemical properties. In this review, we summarize preparation methods effects on composition, properties, catalytic properties various Cu/Mn ratios. The main summarized reactions oxidation carbon monoxide, nitrogen oxide, hydrogen sulfide oxidative removal organic solvents such as benzene, toluene, xylene from air. Some (steam reforming methanol or synthesis gas) manufacture chemicals (methyl formate, propylene benzyl alcohol) catalyzed by also reviewed.
