dc.description.abstractThis work deals with the optimisation of Ce-promoted Co3O4 catalysts supported on alpha alumina for the oxidation of traces amounts of methane. Ten Co-Ce samples were synthesised by incipient wetness coimpregnation with the aim of analysing the influence of the Ce/Co molar ratio and the Co3O4 loading on the physico-chemical properties and resultant catalytic behaviour. Textural, structural, morphological and redox properties along with bulk/surface composition were thoroughly characterised. Lattice distortion provoked by insertion of controlled amounts of Ce increased the abundance of Co3+ and improved consequently the redox properties and the mobility of lattice oxygen species of the Co-Ce catalysts. Analysis of kinetic data in the 200 600 ◦C temperature range evidenced that the optimal catalyst formulation was 10 %Co3O4wt. with a Ce/Co molar ratio of 0.05. In addition, this sample showed a reasonable stability with time on stream under cycled dry/humid conditions.es_ES
