A series of CeO₂-MnO_x-Al₂O₃ mixed oxide catalysts (Ce:Mn:Al mole ratio = 6:4:x, x = 0.25, 0.5, 1, 2) were prepared by a simple one-step inverse co-precipitation method to investigate the influence of the incorporation of Al³⁺ into CeO₂-MnO_x mixed oxides. CeO₂-MnO_x, CeO₂-Al₂O₃, and MnO_x-Al₂O₃ mixed oxides, and CeO₂ were prepared by the same method for comparison. The samples were characterized by XRD, Raman, N₂ physisorption, H₂-TPR, XPS, and in situ DRIFTS. The catalytic reduction of NO by CO was chosen as a model reaction to evaluate the catalytic performance. The incorporation of a small amount of Al³⁺ into CeO₂-MnO_x mixed oxides resulted in a decrease of crystallite size, with the increase of the BET specific surface area and pore volume, as well as the increase of Ce³⁺ and Mn⁴⁺. The former benefits good contact between catalyst and reactants, and the latter promotes the adsorption of CO and the desorption, conversion and dissociation of adsorbed NO. All these enhanced the catalytic performance for the NO+CO model reaction. A reaction mechanism was proposed to explain the excellent catalytic performance of CeO₂-MnO_x-Al₂O₃ catalysts for NO reduction by CO.
