摘要

提出了一种利用大气扫描电子显微镜对液体中电化学反应进行原位观察的新装置。所提出的液相电化学SEM系统由电化学芯片(e-chip)上的一个工作电极(WE)和插入液体电解质中的另外两个电极组成;在WE发生的电化学反应是由连接到三个电极的外部恒电位器/恒流器精确控制的。将CuSO4水溶液中的铜沉积到WE上，利用该装置实现了纳米级图像和可靠的电化学数据的同时采集。

Reliable Electrochemical Setup for in situ Observations with an Atmospheric SEM.

A novel setup for the in situ observation of electrochemical reactions in liquids through atmospheric scanning electron microscopy is presented. The proposed liquid-phase electrochemical SEM system consists of a working electrode (WE) on an electrochemical chip (e-chip) and other two electrodes inserted into a liquid electrolyte; electrochemical reactions occurring at the WE are controlled precisely with an external potentiostat/galvanostat connected to the three electrodes. Copper deposition from a CuSO4 aqueous solution was conducted onto the WE, and simultaneous acquisition of nanoscale images and reliable electrochemical data was achieved with the proposed setup.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
