We examined several metal-doped La2O3 catalysts for OCM reaction. Among them, the Fe-doped La2O3 catalyst indicated good potential for OCM reaction for high O2 conversion and high C2 selectivity. This catalyst was composed of mixture phases of LaFeO3 and La2O3. LaFeO3 related to O2 activation, and La2O3 was associated with C2 generation. The La/Fe ratio on the catalyst affected the C2 yield, changing the balance of LaFeO3 and La2O3 in the catalyst. At La/Fe=20, Fe-doped La2O3 catalyst exhibited the highest C2 yield due to the most effective balance of these two phases.
