| 英文摘要 | High catalytic activity of cobalt nano-oxide supported on hydroxyapatite-encapsulated magnetic gamma-fe2o3 nanocrystallites had been prepared. hr-tem characterization demonstrated the formation of gamma-fe2o3 nanocrystallites within the hap matrix with a mean diameter of 1-3 nm. the mixed co3o4 and cofe2o4 oxides were existed on the surface of cohap-gamma-fe2o3. the cohap-gamma-fe2o3 exhibited good catalytic activity for the oxidation of various alkenes based on a cooperation effect between these two oxides. the magnetic properties of the cohap-gamma-fe2o3 provided a convenient route for separation of the catalyst from the reaction mixture by application of an external permanent magnet. the spent catalyst could be recycled without appreciable loss of catalytic activity.
