Principle And Application Of The Electrochemical Quartz Crystal Microbalance

电化学石英晶体微天平（EQCM）是一种新的、非常有效的电极表面分析方法。其应用概念简单，设备价格低，在电化学电极过程研究中可望得到广泛的应用。本文介绍EQCM基本原理、电极构造、自行设计的电解池构造及实验工作线路图, 并综述了EQCM 技术在表面电化学和催化电化学研究中的一些应用。

The Electrochemical Quartz Crystal Microbalance (EQCM) is a distinctive tool to monitor the surface process of electrode. It can simultaneously measure the changes of surface mass, current and quantity of charge in a potential scan. In correlating EQCM frequency change with electrochemical data, a plot of versus Q will give the apparent mass change per transferred electron. So it is useful to study the reactions which taken place on the electrode surface. At the same time, EQCM can take response to the adsorption and desorption of non-electrochemically reactive species, allows us to determine the non-electrochemical process of electrode. In this thesis, the basic principle、construction of the electrode and self-made cell、 experimental setup in EQCM and its application in electrochemistry and electro-catalysis was reviewed.
