| 英文摘要 | High dispersion gamma-fe2o3 combined with au nanoparticles (denoted as gamma-fe2o3-au nps) coated by mesoporous silica spheres (denoted as m-sio2) were synthesized by a facile one-pot method process. the dispersion of gamma-fe2o3 seed is extremely important to the formation of gamma-fe2o3-au@m-sio2 composite, by using a certain amount of neutral beta-cd as stabilizing agent, high dispersion gamma-fe2o3 nps with 16 nm can be prepared. besides, different number of gamma-fe2o3-au nps within composite can be tuned with the addition amount of gamma-fe2o3 seed. tem images showed the ordered morphology, good dispersion, and uniform particle size of gamma-fe2o3-au nps inside composite. furthermore, xrd, m-h curves and n-2 sorption characterization confirmed gamma-fe2o3-au@m-sio2 composite possessed good magnetic property, uniform mesopore distribution and high surface area. |
