Abstract: Focusing on current research hotspots in hydrogen production via water electrolysis, this paper recommends a comprehensive university chemistry experiment titled “Study on the Oxygen Evolution Performance of Seawater Electrolysis Using NO₃^-/CO₃^2- Intercalated NiFe-LDH”. In this experiment, NO₃^-/CO₃^2- intercalated NiFe-LDH catalysts are prepared sequentially using electrochemical deposition and ion exchange methods. Their phase and morphological structures are characterized by X-ray diffraction, infrared spectroscopy, and scanning electron microscopy. The oxygen evolution reaction (OER) activity, selectivity, chlorine corrosion resistance, and stability of the catalysts are systematically investigated in alkaline simulated seawater. The performance differences between NO₃^- and CO₃^2- intercalated NiFe-LDH are compared, and the structure–activity relationship is analyzed with reference to the literature. This comprehensive experiment achieves a deep integration of cutting-edge research with teaching. It follows the general paradigm of scientific inquiry and involves multidisciplinary knowledge from physical chemistry, analytical chemistry, and materials chemistry. The experiment not only consolidates students’ fundamental theoretical knowledge but also bridges the gap between theory and practice, effectively cultivating students’ comprehensive experimental skills and research innovation capabilities. It is recommended for inclusion in the comprehensive experimental curriculum for senior chemistry majors.
