A comprehensive experiment of NiCu/Ni(OH)₂ electrocatalysts is designed for the alkaline hydrogen evolution reaction（HER）, based on the science and education integration model. The efficient HER electrocatalyst was constructed in situ on the nickel foam substrate by electrochemical deposition and electrooxidation. Meanwhile, large instruments such as field emission scanning electron microscopy (FESEM), X-ray energy dispersive spectrometer (EDS), X-ray diffractometer (XRD) and X-ray photoelectron spectroscopy (XPS) were utilized to analyze the phase information of the catalyst. Linear sweep voltammetry (LSV), electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV) and chronopotential potentiometry (CP) were used to investigate the hydrogen evolution reaction of the catalyst. The comprehensive experiment broadens students’ vision and significantly improves students’ comprehensive experimental skills and innovative thinking ability.
