Meanwhile, Figure 2 c shows that with the increase in PVP content, the pH value of the cathode chamber solution changes minimally; however, with the prolongation of the electrolysis time, the overall pH value of the cathode chamber solution exhibits an increasing trend and ultimately stabilizes between 8.5 and 9.0.
