Cobalt-containing catalysts for the high-temperature combustion of methane

Cobalt was supported on ZrO2, La-doped ZrO2 and La2O3 through atomic layer epitaxy (ALE) and wet impregnation. The rate data obtained at 770 K is comp ared with literature information about cobalt inserted in other matrixes. T he ALE technique using ZrO2 and La-doped ZrO2 yielded the best cobalt-conta ining catalysts. Bulk and surface characterization techniques provided key clues to understand the origin of the large difference in catalytic activit y reported for cobalt-containing formulations.
