Hydrodynamic voltametric technique was employed to validate the methanol assisted oxygen evolution reaction (OER) in KOH medium. The advantage of the RRDE setup used in this work hinges on the selective reduction of oxygen evolved by the GC disk electrode over the Au ring electrode . Here, we have performed linear sweep voltammetry (LSV) at the GC disk electrode in the potential window for OER by sweeping the potential from 1.0 V to 1.7 V at a scan rate of 5 mV s -1 and simultaneously we have done chronoamperometry (CA) on the Au ring electrode by applying a constant bias of 0.7 V vs. RHE to ensure efficient O2 reduction. (Figure ). RRDE studies demonstrate that the OER in methanol contained system starts at a potential which is 100 mV lower than pure KOH electrolyte, proving the assisted OER in presence of methanol (Figure ). These results are in agreement with studies done on glassy carbon electrode in non-hydrodynamic condition. Here, methanol electrooxidation is a mass transfer process because it is dissolved in a reasonably small concentration (0.5 M). On the other hand, water is in large abundance so it is a kinetically controlled process. We measured the charge associated with each system to further support the methanol assisted water electrooxidation.
