摘要
Nanometer perovskite-type complex oxide LaMnO3 with average size of 18.7nm was prepared by sol-gel method, and it exhibited much higher catelytic activity for complete oxidation of methane than that of LaMnO3 with large particle size. The increasing of catulytic activity may be attributed to the increasing of surface area and the change of surface structure for nanometer LaMnO3.
