Se ha efectuado un estudio de la oxidación de C3H6 bajo condiciones de exceso de aire sobre catalizadores de Pt y óxidos metálicos básicos (Co, Cu, Ni, Mo) soportados sobre CeO2 / γ-Al2O3 La incorporación de dichos óxidos metálicos en el sistema Pt/(CeO2 / γ-A12O3) altera la actividad y selectividad del Pt para la conversión del C3H6 a CO2 y H2O. El estudio de actividad mostró que se obtiene un comportamiento sinergista en cada uno de los sistemas bimetálicos estudiados, si se les compara con los sistemas monometálicos. La temperatura a la cual se alcanza el 80% de la conversión se reduce sustancialmente con los sistemas bimetálicos.
