Embodiment 1
[0024] Preparation of glassy carbon electrode modified with core-shell nano bimetallic Fe / Pd catalyst:
[0025] First polish the glassy carbon electrode with 3500# metallographic sandpaper, and then polish the mirror surface of the paper with 0.5μm alumina powder. Before the experiment started, the glassy carbon electrode was first placed in HNO 3 Solution (HNO 3 :H 2 (O volume ratio 1:1) ultrasonic 5min, and then rinse with ultrapure water. The electrochemical experiments were all carried out in the electrolytic cell of the traditional three-electrode system: a clean glassy carbon electrode was used as the working electrode, a Pt sheet was used as the counter electrode, and a saturated calomel electrode was used as the reference electrode.
[0026] NaCl and FeCl 2 The mixed solution of NaCl is used as the deposition solution, and the concentration of NaCl is 0.25mol dm -3 , FeCl 2 The concentration is 10mmol dm -3 , control the temperature at 30°C, and deposit a large ...
