A facile method to promote LaMnO3 perovskite catalyst for combustion of methane

Abstract: This work concentrates on the improvement of LaMnO3 perovskite catalysts for methane combustion by an effective and mild citric acid etching strategy. The etched catalysts showed improved catalytic activity due to higher surface area, abundant vacancies, higher surface Mn4+/Mn3+ ratio and more active oxygen species. Furthermore, the pre-treated catalysts maintained good stability because of the maintenance of perovskite structure.
