Designing anode electrodes with long-term stability and efficiency for seawater electrolysis is crucial addressing key challenges in sustainable hydrogen production clean energy systems. Here, we developed self-supporting bimetallic Ni–Co-MOF electrodes, demonstrating exceptional performance durability alkaline due to their high voltammetric charge density increased electrochemically accessible active sites. The reaction kinetics of the water oxidation presence Cl– ions (at concentrations ranging from 0.5 M 3.5 M) were investigated through electrochemical impedance spectroscopy (EIS) analysis, focusing on kinetic parameters, suggesting that rate-determining step (RDS) chemical process following initial electron transfer. Notably, electrolyte medium do not alter OER rate-limiting step, as indicated by negligible variations anodic transfer coefficient values. However, blocking sites evident decrease interfacial capacitance (Cchem) values increasing concentration. These findings offer a deeper understanding chloride-containing environments correlating parameters site availability. This work highlights critical considerations designing efficient durable anodes electrolysis.
