Embodiment 1
[0014] Use 0.05μm α-Al for copper electrode 2 O 3 The suspension paste is polished to the mirror surface, and then ultrasonically cleaned with absolute ethanol and double distilled water in an ultrasonic cleaner, 100μL 0.4molL -1 Added copper sulfate solution to 10mL 1mmolL -1 The sulfuric acid solution was used as the electrolyte, the copper electrode was used as the working electrode and the counter electrode, and the saturated calomel electrode was used as the reference electrode, and the deposition was carried out at a potential of -1.00V for 60s. Measure the open circuit potential in a two-electrode system and run for 20s.
[0015] Measure the open-circuit potential-time curve at 293.15K, 297.15K, 299.15K, 303.15K, and 305.15K respectively, and perform 5 parallel experiments at each temperature and take the average value and statistics as shown in the table below.
