Ni/La-Ce-Al₂O₃, Pd/La-Ce-Al₂O₃, Pd/Ni/La-Ce-Al₂O₃ catalysts were prepared with cordierite (2MgO·2Al₂O₃·5SiO₂)as support by impregnation method. The influence of Ni on the catalytic activity of the catalysts(ω(Pd)=0.08%)for control of automotive exhausts was studied by TPR, CO-TPD, O₂-TPD, C₃H₆-TPD. The activity of the catalysts in reduction of NO and oxidation of C₃H₈ and CO was found to be increased in the order Pd/Ni/La-Ce-Al₂O₃ >Pd/La-Ce-Al₂O₃ >Ni/La-Ce-Al₂O₃. It is suggested that single Ni is low in activity, but being a promotor, it increase the activity of Pd/La-Ce-Al₂O₃. The decrease of the conversion temperature(T_100%)of NO, CO and C₃H₈ in mentioned reactions over this catalyst was <10℃, 10℃ and 50℃ respectively. Meanwhile, Ni also decreases the reduction temperature of oxygen species in catalyst and the desorption temperature of CO, but increases the desorption temperature of O₂.
