CuO纳米材料的制备及应用研究进展

Research progress of preparation and applications of nano-copper oxide

CuO是一种重要的p型半导体材料,已经被广泛的应用于超导材料、催化剂、磁存储材料、气体传感器、生物医学和锂离子电池等领域。各种形貌的CuO纳米材料,如纳米线、纳米棒、纳米带、纳米花等,已经通过铜的热氧化法、水热合成法和湿化学法等制备出来。CuO纳米材料因其广泛的应用越来越受到人们的关注,与此同时,目前制备方面存在的问题也应该进行相应的改进。

As an important p-type semiconductor with a narrow band gap, copper oxide （CuO） nanomaterials have been widely applied in many flieds, such as superconductors, photocatalysis, magnetic storage media,gas sensor, biomedicine, lithium-ion batteries and so on. Many CuO nanomaterials with different morphologies, such as nanowires, nanorods, nanobelts and nanoflowers, have been synthesized by the common strategies of thermal oxidation of copper sheet, hydrothermal and wet chemical methods. The materials are drawing more and more attention due to its applications, and some disadvantages in preperation should be improved.
