Methane combustion over perovskite catalysts was investigated using a fixed-bed reactor at 1 bar. Co, Mn, Fe, and Ni were used as the B-site of the perovskite catalysts (ABO(3)) and La was used as the A-site. The effect of the calcination temperature on methane combustion and the structure of the perovskite were also investigated. Using XRD, surface area measurements, and O2-TPD, the effects of the perovskite structure, oxygen species adsorbed, and surface area on methane combustion were all examined. The formation of a perovskite structure was affected by the calcination temperature. A catalyst desorbing oxygen at a lower temperature was better for methane combustion, whereas an oxygen species desorbing at a lower temperature was found to be responsible for methane combustion.
