Progress in Study on Magnetic Catalysts

Magnetic catalysts are a new class of catalysts which are of magnetic sensitivity. Especially, nanosized magnetic catalysts have the magnetic sensitivity and the unique properties of nano-materials as well as those of catalytic materials. In the process of chemical engineering, the application of magnetic catalysts could enhance chemical reaction and separation of catalysts or products, which simplifies the whole process and reduces cost of investment. In this paper, the properties of magnetic catalysts, especially nano-sized magnetic catalysts, are illustrated and the application of magnetic catalysts in solid-acid catalysis, solid-base catalysis, phase-transfer catalysis, photocatalysis and biocatalysis is reviewed. The problem and development in this area are also put forward.
