[Preparation, characterization and three way catalytic performance for Pd/CZ/Al2O3 catalyst].
Pd/CZ/Al2O3 catalyst was prepared by impregnating a noble metal solution to the support CZ/Al2O3 which was prefabricated by co-impregnation. The investigation results show that Pd/CZ/Al2O3 has a superior three-way catalytic performance, which is comparable to Pd/CZ for the fresh sample and a better one after thermal ageing. Based on the XRD, BET and TPR characterizations, the internal relationship between catalytic performance, composition and structure was discussed. The relatively high activity after thermal ageing is ascribed to the maintenance of the Strong Metal-Support Interaction (SMSI).
