Can it help to improve the durability and corrosion resistance of the catalyst by minimizing the formation of surface hydroxide species or dissolution of the catalyst material?
Please cite some reference.
Your question is too general to be answered. If you are asking about electrochemical water oxidation, the anode surface always has a high positive potential.
Yurii V Geletii Sir, I have made a little modification in my question. Earlier I wrote, surface potential, that's why maybe it was confusing since during the process a bias is already applied. My question is without any bias how the zeta potential of a catalyst plays a role in OER? Advantages of having a positive and negative zeta potential?
I can understand that if the medium is alkaline, having a positive zeta potential will help in adsorption of OH- ions. But what if its negative? And I have found some papers stating that a positive potential can help in
durability and corrosion resistance of the catalyst by minimizing the formation of surface hydroxide species or dissolution of the catalyst material. Therefore, my question is how?
Z-potential of the electrode surface modified by a catalyst depends on pH and applied potential.
