摘要：

The CO and CH4 deep oxidation properties of the rare-earth-based perovskites, La1-xSrxM1-yByO3- δ (M = Co, Cr, Fe, Mn, Y; B = Nb, Ti) and the superconducting systems with the K2NiF4 structure, La2-xSrxCuO4-δ and Nd2-xCexCuO4-δ were investigated. For CO oxidation p-type conducting materials were found to exhibit the highest catalytic activity. For CH4 oxidation, the activity appears to depend on small electronic conductivity both for p-type and n-type conductors combined with a good oxide ion conduction. © 1993 Academic Press, Inc.
