摘　　要：纳米CuO是一种具有小尺寸效应、表面与界面效应、量子尺寸效应以及宏观量子隧道效应的纳米材料,广泛运用于催化、医药、抗菌及传感器方面。微乳法作为制备纳米CuO的有效的方法之一,能够制备出稳定性高、单分散性好、粒径小的纳米CuO颗粒。采用X射线衍射仪研究了纳米CuO的组成,采用扫描电镜研究了纳米CuO的尺寸和形貌,采用电化学工作站研究了纳米CuO的电化学性质。实验结果表明:所制备样品即为纳米CuO。纳米CuO的尺寸随着水油摩尔比的增加而逐步增大,但是纳米CuO的粒径分布越不均匀,说明它的单分散性并不是很好。纳米CuO的析氢电催化性能比20%Pt/C差。Nano CuO is a kind of nanomaterials with small size effect,surface and interface effect,quantum size eff ect and macroscopic quantum tunneling eff ect,which will be widely used in catalysis,medicine,antibacterial and sensor.As one of the eff ective methods for preparing nanometer CuO,the microemulsion method can prepare nanometer CuO particles with high stability,good monodispersion and small particle size.The composition of nano CuO was investigated by X-ray diffraction instrument.The size and morphology of nanoCuO were investigated using SEM.The electrochemical properties of nano CuO were studied using an electrochemical workstation.The experimental results show that the prepared sample is obtained.The size of nano CuO gradually increased with the molar ratio of water and oil,but the less uniform the particle size distribution of nano CuO indicates that its monodispersity is not very good.The electrocatalytic performance of nano CuO is worse than that of 20%Pt/C.
