Abstract: This work introduces the cutting-edge topic of electrocatalytic two-electron oxygen reduction for hydrogen peroxide production into undergraduate innovative extended laboratory teaching. Using octamethyl copper phthalocyanine as the cathode catalyst, a complete system for the highly selective conversion of oxygen to hydrogen peroxide is constructed. The experimental content covers catalyst synthesis, electrode preparation and characterization, electrochemical testing, and quantitative product analysis, integrating organic synthesis, electrochemistry, and quantitative analysis into a comprehensive chemistry laboratory training program with multiple interconnected modules. Specific methods include rotating ring-disk electrode (RRDE) tests, potentiostatic tests in a gas diffusion electrolytic cell, and ceric sulfate colorimetric quantitative analysis. Through systematic evaluation of the catalytic system’s performance, students can master the measurement methods for key indicators such as hydrogen peroxide selectivity, electron transfer number, Faradaic efficiency, and yield. This experiment organically combines the preparation of organic supramolecular materials, electrochemical testing, and quantitative analysis in analytical chemistry, helping students understand the practical significance of green hydrogen peroxide synthesis and broaden their disciplinary horizons. The experimental design is both scientific and operational; the reagents and equipment are available in most university laboratories, and the results show good reproducibility. It helps stimulate students’ interest in inquiry, cultivate innovative awareness and scientific literacy, and has good teaching feasibility and promotional value.
