Title
Ce-incorporation in mixed oxides obtained by the self-combustion method for the preparation of high performance catalysts for the CO2 reforming of methane
Abstract

Ce-incorporation in Ni–Mg–Al mixed oxides obtained by the self-combustion method was followed by the preparation of high performance catalysts for the CO2 reforming of methane. The morphological, textural and structural characteristics and basic properties were determined. The mixed oxides were precursors of Ni0 nano-particles less than 10 nm, and they were partially reconstructed by the CeO2-incorporation without a morphological change. The self-combustion method improves the surface areas and basicity of the co-precipitation method. Catalysts with higher activities and selectivities and reduced coke formation were achieved by the self-combustion method. H2/CO ratios between 0.8 and 1.1 were obtained which are suitable for further applications.
