Abstract: To enhance the ability of applied chemistry students to apply their knowledge effectively, we designed a comprehensive experimental process utilizing cobalt hydroxide nanosheets/nickel foam as multifunctional electrodes for water electrolysis. The experiment encompasses key topics, including the Nernst equation, the principles of water electrolysis, the preparation and characterization of the cobalt hydroxide nanosheet/nickel foam electrode, performance testing for water electrolysis, analysis of experimental results, and discussion of optimization strategies. This comprehensive experimental design reinforces foundational knowledge in electrochemistry and deepens students’ understanding of the Nernst equation and electrolysis. It encourages students to integrate theory with practice, fosters their interest in scientific research, and equips them with systematic research methodologies, ultimately enhancing their ability to analyze and solve problems.
