摘　　要：纳米FeNi合金因其独特的电磁及催化性能在磁记录、催化剂、吸波材料及生物医学等领域存在广阔的应用前景。由于材料的形貌对其性能有着重要的影响,本文重点介绍了不同形貌(球形、一维形貌、纳米点阵、纳米环、纳米片、纳米花、树枝状及无特定形貌)纳米FeNi合金的制备方法,叙述了各方法制备纳米FeNi合金的基本原理及调控规律,并对各方法的优缺点作出了简要评价。同时,对材料形貌与尺寸对其性能影响的机理及规律作出了简要说明,阐述了其形貌及结构特征对材料性质的影响,指出了不同形貌纳米FeNi合金的优势应用领域。最后,对该领域未来的研究方向作出了展望。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.
