摘要：

介绍一个电解水制氢催化剂的合成、物性表征及其性能评价的综合实验。本实验采用水热法和湿化学法制备了Cu-MoS2/CNTs电催化剂，之后应用伏安法和交流阻抗技术评价了催化剂的性能，以巩固学生对于不可逆电极和超电势概念的理解和学习。本实验通过合成和筛选最佳组分的电催化剂，有助于激发学生的科研兴趣和提高学生综合实验能力。

Abstract:

This paper introduces a comprehensive research experiment regarding the synthesis and characterization of electrocatalysts for electrochemical water splitting. In this experiment, the electrocatalysts (Cu-MoS2/CNTs) were prepared by hydrothermal and wet chemical methods. Then, the electrochemical performance of the catalysts was evaluated by voltammetry and electrochemical impedance spectroscopy (EIS) techniques, which helped consolidate students' understanding and learning of the concepts of irreversible electrode and overpotential. They are helpful to stimulate students' scientific research interests and improve students' comprehensive experimental abilities through the synthesis and optimization of electrocatalysts.
