La(1-x)Sr(x)CoO3 perovskite and Sr(0.8)La(0.2)MnAl(11)O(19-alpha) hexaaluminate catalysts have been examined for methane combustion. While the hexaaluminate catalyst is more stable, it is less active for methane combustion compared to perovskites. More thermally stable catalysts have been synthesized by adding Ba and La to alumina to retard the formation of alpha-alumina. BET surface area as high as 26 sq. m/g has been observed for Ba-alumina after calcination at 1,200 deg C. Combustion results show that the catalyst can reduce NOx emission probably by destroying N2O, NOx precursor during combustion.
