Abstract

Un catalizador de purificacion para gas de escape mejora las actividades de los metales preciosos, evitando caidas o disminuciones de actividades a alta temperatura, y que exhibe un desempeno suficiente incluso durante operacion a baja temperatura (inferior a 400 grados C) cuando se arranca un vehiculo o durante marcha en vacio. El oxido de Pd se soporta en el oxido de Al, y el oxido de Al es LnAlO3 (Ln: elementos de tierra-rara).
