摘　　要： 以糠醇为炭源,Fe(NO3)2·9H2O为磁性前躯体,SiO2微球为模板采用一步浸渍法合成了磁性介孔炭,并用化学方法将含胺基官能团嫁接于磁性介孔炭的表面。利用扫描电子显微镜(SEM),红外光谱(FT-IR)和氮气吸-脱附(BET)对经乙二胺表面改性后氨化磁性介孔炭进行表征。结果表明:所合成的氨化磁性介孔炭比表面积为384 m2/g,平均孔容积为0.7 cm3/g,并具有双介孔微球结构。 Magnetic mesoporous carbon was synthesized through one step impregnation method by using furfuryl alcohol as carbon precursor, Fe（NO3）2-9H2O as a iron source and SiO2 microspheres as template. The magnetic mesoporous carbon was subsequently modified with ethylenediamine by treatment with functionalized nitric acid and thionyl chloride to obtain a functionalized magnetic mesoporous carbon. The functionalized materials were characterized by scanning electron microscopy, Fourier transform infrared and N2 adsorption. The results showed that the specific surface area and total pore volumes of functionalized magnetic mesoporous carbon were 343 m2/g and 0.7 cm3/g and have a dual-mesoporous carbon spheres structure.
