| 英文摘要 | a solvothermal post-treatment method was developed to synthesize fe3o4@mesosilica core-shell nanospheres (csns) with a well-preserved morphology, mesoporous structure, and tunable large pore diameters (2.5-17.6 nm) for the first time. n,n-dimethylhexadecylamine (dmha), which was generated in situ during the heat-treatment process, was mainly responsible for this pore-size enlargement, as characterized by nmr spectroscopy. this pore-size expansion can be strengthened with the aid of hexamethyldisilazane (hmds), whilst the nature of the surface of the fe3o4@mesosilica csns can be easily modified with trimethylsilyl groups during the pore-size-expansion process. the hydrophobicity of the fe3o4@mesosilica csns increased for the enlarged mesopores and the adsorption capacity of these csns for benzene (up to 1.5 g g(-1)) is the highest ever reported for fe3o4@mesosilica csns. the resultant fe3o4@mesosilica csns (pore size: 10 nm) showed a 3.6-times higher adsorption capacity of lysozyme than those without the pore expansion (pore size: 2.5 nm), thus making them a good candidate for loading large molecules. |
