Sumario:In this work,anovelsolid is reported,which is active for the selective reduction of NOx with butane and toluene as reducing agents and at the same time can act as a hydrocarbon trap during the engine cold start.The active component for the catalytic reac- tion is exchanged cobalt,while the cesium promotes the adsorption capacity. Another important result is that the presence of cesiumin CsxCoM catalyst does not change the catalytic activity.Moreover, when butane is th ereducing agent,cesium increases the tempera- ture window for NOx reduction.
