中文摘要：
钴氰化钠与铁氰化钠结构类似,而其在固/液界面上的电子转移特性却并不显著.使用扫描电化学显微镜（SECM）构建了fL-pL体积的电化学微体系.在微体系中溶剂蒸发,电解质则会浓缩结晶.当电活性物质与支持电解质的晶格参数匹配时,二者可发生共结晶形成固体溶液.本文采用该方法制得钴氰化钠/氯化钠固体溶液微晶体,结合微加工技术构建了固体电极/固体溶液界面,该钴氰化钠在固体溶液中即有很好的电子转移特性.
英文摘要：
Although the molecular structures are similar to each other,the redox property of Co（CN）63-at solid/liquid interface is not so good as Fe（CN）63-.In this paper,scanning electrochemical microscopy（SECM） was adopted to construct an electrochemical microsystem with a volume of fL pL,in which a micropipette with micrometer-sized orifice was employed as the scanning tip.Due to the evaporation of water,the NaCl electrolyte is concentrated to form a microcrystal.During the crystallization,the redox species Co（CN）63-replaced the sites of NaCl65-unit due to their matching lattice parameters,i.e.,the solid solution.Single Na3Co（CN）6/NaCl crocrystal was assembled in-situ between a pair of gold microelectrodes on a microchip to construct the solid/solid interface,which was found to have good voltammetric behavior.
