Preparation of FeNi Nano-Alloy with Various Morphologies

As an important functional material, FeNi nano-alloy exhibits great potential for using as magnetic recording materials, catalyst, absorbing materials, biomedicine materials and so on for its unique electromagnetic and catalytic properties. Due to the important impact of morphology of the material on its performance, the preparation of FeNi nanostructure with various morphologies including nanosphere, one-dimensional nanostructure, nanodot, nanoring, nanoplate, nanoflower, nanobranch and no particular shape are summarized in this paper. The basic principles and regulation rules of each method are described, and the advantages and disadvantages are evaluated briefly. The mechanism and law of the morphology and size of the material that influence on its properties are also described, and the application fields of FeNi nano-alloy with different morphologies are pointed out. Finally, the future research direction is prospected.
