LaNi1-xCoxO3 (x=0, 0.1, 0.3, 0.7, 1.0) perovskite catalysts were prepared by co-precipitation method and investigated in the catalytic oxidation of NO. LaNi0.7Co0.3O3 showed the best catalytic activity among all the samples, confirming the potential of LaNi0.7Co0.3O3 as a cheap and efficient NO oxidation catalyst. The high reactivity of LaNi0.7Co0.3O3 was mainly due to the moderate amount of adsorbed NO and O-2 and their moderate adsorption strength on the surface of the catalyst, as determined by the XRD, H-2-TPR, NO-TPD, O-2-TPD and XPS studies.
