Abstract
Substitution with calcium affected significantly the surface specific area which ranged in 6-17 m2/g with a maximum value for an optimal composition x = 0.6. The light-off temperature for 50% methane conversion was found to be the lowest for La0.4Ca0.6MnO3.03 composition. Samples with oxygen overstoichiometry showed better catalytic performances (specific and areal activities) than those with oxygen substoichiometry. An optimal fraction, x = 0.6 of Ca enhanced significantly these performances.
