采用电化学循环-浸渍法制备了半胱氨酸单分子层保护的铜团簇（CuMPCs）桥联的六氰合铁酸铜（CuHCF）多层膜。利用循环伏安法、扫描电子显微镜（SEM）和原子力显微镜（AFM）对多层膜的形成进行了表征。循环伏安测试结果表明，薄膜的生长与层数的增加呈指数关系。AFM和SEM图像显示，所获得的薄膜是薄的，并表现出三维结构。该纳米结构薄膜组装体表现出有趣的催化性能，可应用于重要的传感和催化。研究了该膜修饰电极对过氧化氢的催化活性和稳定性。
Multilayer copper hexacyanoferrate (CuHCF) films bridged by cysteine monolayer protected copper clusters (CuMPCs) were prepared by the sequential electrochemical cyclcing and dipping process. Cyclic voltammetry, scanning electron microscopy (SEM) and atomic force microscopy (AFM) were used to characterize the formation of the multilayer films. Cyclic voltammetric measurements indicated that the films grew exponentially with the increase of the layer numbers. AFM and SEM images revealed that the obtained films were thin and exhibited a three-dimensional structure. The nanostructured thin-film assemblies exhibited interesting catalytic properties that could be applied in important sensing and catalysis. Good catalytic activity and stability of the film modified electrode for hydrogen peroxide detection was studied.
