Abstract: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. |
Key words:magnetically separable nanocatalyst;magnetic nanoparticle;separation and recycle |
