Abstract: To advance the integration of research and teaching in talent cultivation and to build an advanced experimental teaching system oriented toward the frontiers of carbon neutrality, this work draws on the instructors’ research achievements to design a comprehensive experiment involving the fabrication of a Cu-based integrated electrode and electrocatalytic CO2 reduction. An integrated Cu2O electrode was constructed in situ by electrodeposition, followed by potentiostatic electrolysis in an H-type electrochemical cell. The products were quantitatively analyzed by gas chromatography, establishing a complete experimental workflow that encompasses material preparation, structural characterization, performance evaluation, and data processing.
