, the electric current, which is a critical part of the process, was not taken into account. ALAM et al [5] implemented a low temperature electrolytic experiment. CuSO4 solution was adopted as bath solution. A lead alloy and a stainless steel were used as the anode and cathode, respectively. A DC power supply was utilized to supply the current, and O2 bubbles were generated underneath the anode......
