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.

Key words: MoS2, Cu nanoparticles, Carbon nanotubes, Electrochemical water splitting, Comprehensive experiment
