Journal of Electrochemistry
Electrochemical reduction of carbon dioxide (CO2) was studied in the H-type electrolytic cell. It was found that the voltage between the cathode and the anode would increase during the long time electrolysis process, for this reason the electrolytic process would be unsustainable. After the experimental investigations carried out by constant potential electrolysis, constant current electrolysis, pH test and KHCO3 concentration analysis of anode electrolyte before and after the electrolysis, the increase in cell voltage might be caused by the following process: H+, that was generated from the anodic oxygen evolution reaction, reacted with HCO3 …
