Citation Effect of the Preparation Method on the Structural and Catalytic Properties of MnOx-CeO2 Manganese Cerium Mixed Oxides [Текст] / A. Benadda, A. Djadoun, H. Guessis, A.

Abstract MnOx-CeO2 catalysts (molar ratio Mn/Ce 1) were prepared using two methods: co-precipitation and citrate methods. The prepared solids were calcined at 500°C, and characterized by XRD, nitrogen adsorp-tion-desorption technique and SEM morphological, they were, then, tested in the toluene combustion reac-tion. The catalytic performances of the prepared solids were evaluated in the temperature range 150-400°C. The XRD analysis of the two solids showed that the only crystalline phase detected is cerium oxide. BET surface area measurements showed that the incorporation of manganese led to an increase in the spe-cific surface area of ceria, the solid prepared by the co-precipitation method led to the highest specific sur-face area (156 m²/g). The solids showed good performances in the toluene combustion reaction that depend strongly on the preparation method. The best catalytic activity was obtained for the catalyst prepared by the citrate method achieving a complete conversion of toluene at 250 ° C.
