摘要: 电化学教学的重难点之一,是使学生理解抽象的电化学界面现象。通过经典密度泛函理论(CDFT)计算,可以得到电化学界面上的离子密度分布。课堂上借助CDFT,将电化学界面快速、直观地展示出来,可以帮助学生理解电化学过程机理,并探索其在化学电源、增强采油等前沿领域的应用,有助于大幅度提高教学质量和激发学生的学习兴趣。

Abstract: Understanding abstract electrochemical interface phenomena is a key challenge in electrochemical education. Classical density functional theory (CDFT) calculations enable the visualization of ion density distributions at electrochemical interfaces. Introducing CDFT in the classroom facilitates the clear visualization of electrochemical interfaces, helping students grasp the mechanisms of electrochemical processes. Furthermore, this approach facilitates exploration of applications in advanced fields such as chemical power sources and enhanced oil recovery. Consequently, this approach significantly enhances teaching effectiveness and inspires students' enthusiasm for learning.
