Abstract The correlations between the catalytic properties and the surface states, which were measured by X-ray photoelectron spectroscopy (XPS) were investigated for the perovskite-type cerium doped lanthanum cobalt oxides (La1-x Ce x CoO3). The activities of the catalytic oxidation for the 1123 K calcined samples were correlated with the atomic ratio of cobalt on the surface. On the other hand, the activities of the catalytic oxidation for the 1673 K calcined samples had a peak atx = 0.02. The ionicity between surface cobalt and lattice oxygen increased by substituting cerium for lanthanum, and had a peak atx = 0.02.
