Abstract
A series of Mn-Ce catalysts with different ratio of Mn-to-Ce were prepared by a redox-precipitation method, and their catalytic performance in lean methane combustion was investigated. A plethora of structural (XRD), textural (BET, FSEM), and spectroscopic (XPS) methods have been applied for characterization. The results show that the catalytic performance of the investigated samples is strongly related to the ratios of Mn-to-Ce. Mn-Ce catalyst with an atomic Mn/Ce ratio of 9/1 provided with a larger specific surface area, pore volumes, abundant manganese species of higher valence (Mn4+), Cerium species of lower valence(Ce3+), and lattice oxygen.
