Mn-modified Co3O4 catalysts with spinel structure with various Co/Mn ratios prepared by co-precipitation method were characterized by XRD, Raman, TEM, HRTEM, XPS and H2-TPR, and used in catalytic combustion of 1,2-dichlorobenzene (o-DCB), as a model of dioxins. The results revealed that the catalyst with Co/Mn ratio of nine presented the highest activity with T90 of 347°C and high stability at least...
Co-Mn/CeO2 mixed oxide catalysts have been prepared by immersion method and evaluated in the catalytic combustion of methyl acetate. CeO2 is prepared by co-precipitation method as supporter. Then Co-Mn/CeO2 mixed oxide is washcoated on ceramic honeycomb. The catalysts are characterized by X-ray diffraction (XRD), Temperature-programmed reduction with hydrogen (H2-TPR) and BET surface area. According...
Hexaaluminates and perovskites are two promising candidates for use in catalytic combustion applications. In the present study two hexaaluminates, LaMnAl 11 O 19 and LaCoAl 11 O 19 , were compared with two perovskites, LaMnO 3 and LaCoO 3 , with respect to their thermal stability and catalytic activity for combustion of methane and gasified biomass....
