Title
Catalytic properties of Fe and Mn modified lanthanum hexaaluminates for catalytic combustion of methane
Abstract

A series of Fe and Mn ions modified lanthanum hexaaluminates, LaFeMnxAl11−xO19−δ (x = 0, 0.5, 1, 2, 3, 4, 5) as new catalysts for combustion of methane, was prepared by sol–gel method and calcined at high temperature. Fe and Mn ions were used as active components to replace part of aluminum ions in the hexaaluminates lattices. The structure and properties of these samples were characterized by XRD, BET, TG-DTA and XPS. The series of hexaaluminates exhibited significant catalytic activity and stability at high temperature. The LaFeMnAl10O19−δ catalyst possesses a larger specific surface area and shows a higher activity than the others in methane combustion.
