Abstract: 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.
