中文摘要：

纳米氧化铜不同于常规氧化铜，由于其晶粒尺寸小，比表面积大，使其具有独特的电、磁、光、化学等特性。近些年，其应用范围越来越广阔。本文综述了纳米氧化铜粉体制备的具体方法，详细介绍了液相法、固相法等制备技术的国内外研究进展；同时分析介绍了纳米氧化铜在常温脱硫、催化反应和抗杀菌等方面的应用前景，认为纳米氧化铜在污染物治理方面的应用需深入研究，以拓宽其在环境工程中的应用范围；最后指出制备过程中的环境污染、工艺耗能和反应时间等问题应得到重视，而纳米氧化铜的制备工艺应向着节能、高效、绿色工业的方向发展。

英文摘要：

Different from conventional copper oxide,nano copper oxide has its unique electrical, magnetic,optical,chemical characteristics because of its small grain size and high specific surface area,and has attracted extensive attention in many fields. Many preparation methods of nanometer copper oxide powder are reviewed,with emphasis on liquid phase methods and solid phase methods;also, the prospects of its application in the fields of desulfurization,catalysis,and antibacterial action are discussed and the application of nanometer copper oxide to pollutant control is recommended. In order to broaden the scope of its application in environmental engineering,environmental pollution, energy consumption and reaction time in the process of preparation should be paid more attention. Energy saving,high efficiency,green industry should be the direction of preparation of nanometer copper oxide.
