纳米复合材料因具有独特的物理、化学性能而成为纳米领域研究的热点。镍纳米材料作为一种重要的过渡金属纳米材料,在磁学、电化学、催化等领域具有广泛的应用。将它与其他金属、氧化物等材料复合,一方面使其固有性质得到明显改善,另一方面利用其他组成和镍基材料的协同作用,可得到具有新特性的异质材料,因此研究镍基纳米复合材料的合成具有重要的科学意义。由于纳米材料的结构不同,其复合位置和复合方式均存在不同,本文按照复合材料的结构特征,分别从核壳型、负载型、多节段纳米线3种类型对镍纳米复合材料的研究进展进行评述,在介绍这些材料的合成方法、结构特点的基础上,综述各种方法、各类结构的优缺点及应用前景,为类似复合材料的合成提供借鉴。
Due to its unique physical and chemical properties, nanocomposites have become the focus of research in the field of nanotechnology. As an important transition metal nanomaterials, nickel nanomaterials have a wide range of applications in the fields of magnetism, electrochemistry and catalysis. It is combined with other metals, oxides and other materials, on the one hand, its inherent properties have been significantly improved, on the other hand, the use of other components and the synergy of nickel-based materials can be heterogeneous materials with new features, so study nickel The synthesis of nanocomposites has important scientific significance. Due to the different structure of nanomaterials, the composite locations and composite methods are different. According to the structural characteristics of nanocomposites, the progress of nanocomposites from three types of core-shell, supported and multi-segment nanowires Based on the introduction of the synthesis methods and structural features of these materials, the advantages and disadvantages of various methods and various types of structures and their application prospects are summarized, providing references for the synthesis of similar composites.
