The Progress of Researches on Chemical Reduction Synthesis and Catalytic Properties of Copper,Cobalt,Nickel Nanocrystalline

纳米材料是21世纪最具开发潜力的高新技术材料之一,铜、钴、镍等非贵金属纳米材料由于储量高、价格低廉,具有良好的光学、电学、磁学以及催化特性,成为多相催化工业中代替贵金属纳米材料研究的热点。在分析铜、钴、镍纳米颗粒的化学还原法合成过程及其形成机理的基础上,重点综述了其形貌尺寸控制的影响因素,同时对其催化性能进行了阐述。最后对铜、钴、镍纳米材料的研究及发展方向进行了总结与展望。

Nanomaterials are one of the high-technological materials which have the most development potential in the 21st century. Due to their abundant resources, low price, and good optical, electrical, magnetic and catalytic properties, copper, cobalt, nickel and other non-noble metal nanomaterials have become the current research focuses instead of noble metal nanomaterials in the heterogeneous catalysis industry. Based on studies o{ chemical reduction synthesis process and formation mechanism of the copper, cobalt, nickel nanomaterials, the influencing their prepara- tion process, such as morphology and size, are mainly introduced in detail. Besides, the catalytic properties of them are also reviewed. Finally, the research and development directions of copper, cobalt, nickel nanomaterials are sum- marized and prospected.
