Abstract
LaMnO3 catalysts with high catalytic activity for methane combustion have been prepared in an oil–water twophase system The procedure was carried out using oleic acid as phasetransfer agent and ammonia as coprecipitation agent In the meanwhile H2O2 is employed to control the valence of Mn ions when precipitation The control results in perovskites with similar phases having three O2TPD patterns and induces the catalysts possessing distinct catalytic activities The structure and properties of the catalysts were characterized by BET TGDSC XRD and O2TPD techniques
