In an electrochemical cell with Na2SO4 as electrolyte, I ran a comsol simulation with secondary current distribution and transport of diluted species. The results showed that Sulphate ions (SO42-) are moving towards the cathode(-vely charged). On the cathode hydrogen peroxide is generating via 4 e- oxygen reduction reaction and at anode water splitting is happening.
Can anyone help me how to investigate this phenomena?
Dear Dr. Dixit, hydrogen peroxide in described system created in 2e- reaction like O2+2e+2H2O =H2O2 +2OH-. Please, be sure that you correctly describe the reaction on cathode and anode in your system with neutral medium. It is important for simulation since you should correctly indicate which ions are presented and created in your system.
Ekaterina Zolotukhina, I checked my system. It was some error. Thanks for your input.
