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

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 of chemical reduction synthesis process and formation mechanism of the copper, cobalt, nickel nanomaterials, the influencing their preparation 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 summarized and prospected.
