Magnetic nanocomposites with well-defined mesoporous structures, shapes, and tailored properties are of immense scientific and technological interest. This review article is devoted to the progress in the synthesis and applications of magnetic mesoporous materials. The first part briefly reviews various general methods developed for producing magnetic nanoparticles (NPs). The second presents and categorizes the synthesis of magnetic nanocomposites with mesoporous structures. These nanocomposites are broadly categorized into four types: monodisperse magnetic nanocrystals embedded in mesoporous nanospheres, microspheres encapsulating magnetic cores into perpendicularly aligned mesoporous shells, ordered mesoporous materials loaded with magnetic NPs inside the porous channels or cages, and rattle-type magnetic nanocomposites. The third section reviews the potential applications of the magnetic nanocomposites with mesoporous structures in the areas of heath care, catalysis, and environmental separation. The final section offers a summary and future perspectives on the state-of-the art in this area.
具有明确介孔结构、形状和定制性能的磁性纳米复合材料具有巨大的科学和技术兴趣。本文综述了磁性介孔材料的合成及应用进展。第一部分简要回顾了制备磁性纳米颗粒（NPs）的各种通用方法。第二部分介绍并分类了具有介孔结构的磁性纳米复合材料的合成。这些纳米复合材料大致分为四类：单分散磁性纳米晶嵌入介孔纳米球中、微球将磁性核封装在垂直排列的介孔壳中、有序介孔材料将磁性 NPs 负载在多孔通道或笼中、以及 rattletype 磁性纳米复合材料。第三部分综述了具有介孔结构的磁性纳米复合材料在医疗保健、催化和环境分离领域的潜在应用。最后一部分对该领域的最新技术进行了总结和展望。
