磁性钴纳米粒子的制备和应用

Synthesis and application of magnetic cobalt nanoparticles

介绍了制备磁性钴纳米粒子的方法 ,尤其是介绍了近年发展起来的高温液相法 ,即高温液相还原法 ,金属盐醇解法和金属有机化合物热分解法 ;同时就制备颗粒尺寸小、粒度分布均匀的钴纳米粒子所采用的两种表面活性剂从理论上给予了说明。最后简单介绍了磁性金属钴纳米粒子的主要应用。

Some methods for synthesizin g magnetic cobalt nanoparticles are introduced, especially the high temperature li quid phase method including the method of high temperature solution phase reduc tion, metal salt diol reduction and pyrolysis of cobalt carbonyl is elucidated i n this paper. meanwhile, the mechanism controlled the nanoparticles dimension by the two kinds of surfactants is explained theoretically. Last, some important a pplication of magnetic coblat nanoparticles is illustrated in this paper.
