Descripción
This paper analyzes the influence of synthesis conditions on the reducibility and catalytic behavior of Ce0.9Zr0.1O2 mixed oxide synthesized by α-amino acid/metallic nitrate combustion processes, through stoichiometric and non-stoichiometric routes. We concluded that the α-amino acid selected and the α-amino acid/nitrate molar ratio strongly influence the reducibility and catalytic activity in the total combustion of methane. Thus, the Ce0.9Zr0.1O2 catalyst synthesized by the stoichiometric route with glycine showed the higher catalytic activity, which, in conjunction with the well-known ionic and electronic conductivities of ceria-based oxides under reducing conditions, positions this solid as an appropriate anode material for methane-fuelled solid oxide fuel cells.
