Abstract: Perovskite materials La0.75Sr0.25Mn1-xNixO3+δ (x = 0, 0.4, 0.5, and 0.6, and the corresponding samples are denoted LSM, LSMN4, LSMN5, and LSMN6) were prepared by a citric chelating method. Among these samples, LSMN5 is prone to catalyze methane partial oxidation at relatively low temperature and has best catalytic performance at high temperature. This may be interpreted by the large amounts of reducible species and oxygen species on the surface and in the bulk.

Key words: doped lanthanum manganite, nickel, perovskite, methane partial oxidation, solid oxide fuel cell
