Abstract

This paper discusses the modification of MnO_x by doping various metals, such as Cu, supported on cordierite honeycomb ceramics, which were easily synthesized by using the impregnation method. The physicochemical properties were comprehensively featured via the BET, XRD, SEM-EDX and H₂-TPR techniques. Activity results suggested that the introduction of doping metals significantly enhanced the catalytic performance of Cu₁Mn₂O_x compared to single metal oxides. Furthermore, in the catalytic oxidation of benzene and toluene, the monolithic Cu₁Mn₂O_x catalyst demonstrates the best catalytic performance. It was able to completely oxidize the two compounds at 275^oC with a reaction velocity (WHSV) of about 18,000 mL/(g^•hr) and pollutant concentrations of 7000 ppm and 12000 ppm, respectively. The formation of a Cu-Mn solid solution with spinel Cooper-Manganese structure was thought to be the cause of the excellent catalytic performance of monolithic Cu₁Mn₂O_x. This resulted in an increase in the amount of adsorbed oxygen species on the surface and a high lattice oxygen mobility. This can improve catalyst reducibility and oxygen species activity, as demonstrated by significantly higher dehydrogenation temperatures of Cu-Mn composite oxides through H₂-TPR. Meanwhile, the monolithic Cu₁Mn₂O_x catalyst showed good stability in 16 hours of testing and cycle ability test and showed great potential in practical application.
