摘　　要：介绍了磁性纳米催化剂的特性,综述了近年来磁性纳米催化剂在在氢化催化、加氢甲酰化催化、C-C键偶联反应催化、氧化和环氧化催化、酯化反应催化、缩合反应催化、烯烃复分解催化、光催化、生物催化等领域应用的研究进展,旨在探讨磁性纳米催化剂制备方法和应用领域,同时提出其应用过程中存在的问题,并对发展前景进行了展望。Magnetically separable nanocatalysts have the magnetic sensitivity and the unique properties of nano-materials as well as those of catalytic materials.Compared to their parent catalysts in solution,the magnetically separable nanocatalyst not only allow facile separation and recycling of the catalyst under the extern magnetic field,but also keep their previous dynamic performance such as high activity and selectivity due to the body size under the nano meter scale.In this paper,the applications of magnetically separable nanocatalyst in hydrogenation,hydroformylation,C-C coupling reaction,oxidation and epoxidation,esterification,condensation reaction,olefin metathesis,photocatalysis and biocatalysis were reviewed.The problems and the direction of the further research were also put forwarded.
