课程简介(教工部数据)
电化学在能源化学、环境化学和分析化学等领域具有广泛的应用。电化学与其它化学过程相比,其独特之处在于其过程发生在电极与电解液界面,电极表面的强电场使化学反应的动力学以及物质传输都与其它均相和异相过程显著不同。因此,有必要通过学习该课程,理解电化学过程的内在原理。该课程从化学本科的物理化学基础出发,结合物理模型的构建和数学推导,从电极-溶液界面结构、溶液中的传质过程,以及电极表面反应动力学等方面分析电极过程。介绍电势阶跃方法、电势扫描方法,以及阻抗谱方法等实验技术。该课程所学知识是电化学催化、化学电池、电容器,以及电分析化学等领域研究的基础。


Electrochemistry has broad applications in energy chemistry, environmental chemistry and analytical chemistry. Compared with other chemical processes, electrochemical processes have some unique characteristics: Electrochemical processes occur at the interface between electrode and electrolyte, and due to the strong electric field near the surface of electrode, on the kinetics and mass transport of chemical reactions at electrode-electrolyte interface are significantly different from those of other homogeneous and heterogeneous reactions. Therefore, it is necessary to understand the underlying principles of electrochemical reactions through the learning of this course. Students for this course should finished the study of 'Physical Chemistry I' at the undergraduate stage. In this course, we will combine building physical models and mathematical derivation, and analyze the electrode processes from the aspects of structure of electrode-solution interface, mass transport in solution, and kinetics of reactions on the surface of electrode. This course will also introduce some experimental techniques including potential step method, potential sweep method, and impedance method. The knowledge of this course is the fundamental of the researches in the fields of electrochemical catalysis, chemical battery, capacitors, and electrochemical analysis.
