采用两步合成工艺制备了大表面积(约800 m（2) g(-1)）和高磁化强度（约8.3 emu g(-1)）的磁性MCM-41。8 nm氧化铁纳米颗粒(即30 m（2) g(-1)）嵌入MCM-41中，对颗粒形态和孔隙对称性没有明显影响，但有轻微变化(即
Magnetic MCM-41 of large surface area (ca. 800 m(2) g(-1)) and high magnetization (ca. 8.3 emu g(-1)) was prepared at a reasonable iron oxide nanoparticles loading of 10 wt % by a two-step synthesis process. The 8 nm iron oxide nanoparticles (i.e., 30 m(2) g(-1)) were embedded in the MCM-41 with no observable effects on the particle morphology and pore symmetry, but a slight change (i.e.,
