Abstract:

This work successfully synthesized copper oxide（CuO）whiskers using an electrochemical method.Metallic copper was anodized under low-voltage conditions in an alkaline solution containing ethanol/water mixtures and poisoning agents.After burning the composition and morphology of the copper oxide whiskers were determined by XRD and SEM measurements，respectively.The copper oxide whiskers are 0.5—1 μm long，with a diameter of 60—100nm，and the ratio of the length to the diameter ranges from 8∶1 to 10∶1.At the same time the electrochemical behavior of the process was discussed by cyclic voltammetry.A new method is supplied to synthesis the copper oxide whisker.

摘要：

用电化学方法制备了氧化铜晶须。金属铜在含乙醇-水及毒化剂的混合碱性溶液中进行阳极氧化，煅烧后所得样品的成分和形貌用XRD和SEM方法表征。结果表明，晶须的物相是CuO和Cu₂O，直径60～100nm，长度0.5～1μm，长径比8～10，同时用循环伏安法探讨了该过程的电化学行为，为晶须的制备提供了一种新的方法。
