磁性介孔碳材料及其改性修饰

Modification of magnetic mesoporous carbon materials

磁性介孔材料是将磁性纳米粒子与介孔材料复合制备的新型材料,它兼具介孔材料和磁性材料的双重优势,如均匀的空隙大小和高的比表面积、高吸附性、可磁分离性。因磁性粒子的介入还可提高介孔材料的水热稳定性、吸附活性,同时改善介孔材料从液相体系中分离困难的缺点。近年来,在水净化领域、催化反应、药物可控释放等领域得到研究者的青睐。对磁性介孔材料进一步进行修饰和功能化,可提高材料的特殊性能,以满足不同领域的应用要求。

The magnetic mesoporous material is a new kind of material prepared by combining magnetic nanoparticles with mesoporous materials. It has the advantages of both mesoporous materials and magnetic materials, such as uniform void size and high specific surface area, high adsorption,magnetic separation sex.The intervention of magnetic particles can also improve the hydrothermal stability and adsorption activity of the mesoporous materials,and improve the difficulty of separating the mesoporous materials from the liquid phase system. In recent years, in the field of water purification, catalytic reaction, drug controlled release and other fields have been favored by researchers. The magnetic mesoporous materials are further modified and functionalized to improve the special properties of the materials to meet the application requirements of different fields.
