(a) The electrocatalytic oxidation of methanol over LSCO modified GCE electrode was noticeable with onset at 1.34 V, as revealed in Figure , this value is 130 mV lesser than alkaline system (b) 2-fold increment of current density (i.e., ~ 6 mA/cm 2 to ~12 mA/cm 2 ) at same potential, in comparison with the study in alkaline medium. The increased current density and reduced onset potential clearly show the significant electrochemical reactivity of LSCO towards methanol oxidation and provide evidence that methanol addition is possibly facilitating OER.
