摘要本论文中，采用水热法制备出的Fe-MOF为原料，通过在不同温度(500℃和600）煅烧制备出磁性多孔碳/氧化铁复合材料(C-500和C-600)。通过X射线衍射(XRD)、红外光谱(FT-IR) 、透射电镜(TEM) 、振动磁磁强计(VSM法)、接触角分析等对所获得多孔炭复合材料进行结构、形貌、磁性能及亲油疏水性能进行分析。结果表明：C-500形成以Fe3O4为核的多孔碳包覆在外棒状复合材料，BET达到300m2/g，接触角为165.68°超疏水性能；而C-600为γ-Fe2O3颗粒聚集多孔碳包覆的棒状复合材料，BET为250m2/g，接触角为152.13°超疏水性能；油水分离和染料吸附实验表明：C-500对油的吸附量为自重的28倍，对亚甲基蓝的吸附率可达94.97%；C-600吸油为21倍，亚甲基蓝的吸附率为84.33%。C-500和C-600 均有较高的磁化强度实现油水磁性分离并进行回收再利用。毕业论文关键词： MOF；多孔材料；超疏水；磁性分离；24188

Abstract
In this paper, the Fe-MOF precursor was synthesized via a solvothermal method. Then, the porous carbon composite was obtained by annealing MOF at 500℃ and 600℃ (namely C-500 and C-600) respectively. A series of analysis including XRD, FT-IR, TEM, VSM and contact angle to investigate the structure, the morphology, the magnetic and superhydrophobic property. The results indicated that C-500 specimen had the nuclear Fe3O4 and rod-like porous carbon coated, which possessed the specific surface area of 300m2/g and the contact angle 165.68° with superhydrophobic property. Meanwhile, C-600 sample was γ-Fe2O3, with the specific surface area of 250m2/g and the contact angle152.13°. Thereby, Oil removal and MB adsorption studies distinguished that The C-500 material adsorbed oil 28 times its own weight (28 w/w) and MB adsorption .94.97%, when the C-600 composite was 21w/w for oil and 84.33% for MB dye. In addition, the saturation magnetization of the C-500 and C-600 composites were strong enough for efficient magnetic separation and being recyclable
