The open circuit potential of hydrogen peroxide at noble and glassy carbon electrodes in acidic and basic electrolytes

► OCP of H2O2 is a mixed potential of H2O2 electrooxidation and electroreduction. ► OCP of H2O2 is closer to the equilibrium potential of H2O2 electrooxidation. ► OCP of H2O2 is around 0.8 V in acidic solution and around 0 V in basic solution.
