采用阴极电沉积法合成了纳米Cu2 O薄膜.利用扫描电镜和XRD对所得样品的形貌进行了表征，并用紫外可见光谱法和循环伏安法对其性质进行研究.结果表明：纳米Cu2 O为立方结构，在300~500 nm有一个肩峰，在652 nm处有一宽的吸收带，在pH=4.74的HAc/NaAc缓冲溶液中有一对氧化还原峰，峰电流与扫速的1/2次方呈线性关系.%Nano Cu2 O film was synthesized by means of cathodic electrodeposition. The obtained samples were characterized by sem and XRD and its property was studied using UV-vis spectroscopy and cyclic voltammetry. Results show that the nanostructured Cu2 O is cubic structure, it has a shoulder peak in the 300 nm to 500 nm, a wide absorption band at 652 nm and a pair of REDOX peak in the pH=4. 74 d/NaAc in buffer solution. In addition, the peak current and scan rate of 1/2 time are linear relationship.
