To understand the OER activity, the linear sweep voltammograms (LSV) and cyclic voltammograms were recorded by sweeping the potential from 1.0 V to 1.54 V in basic electrolyte. Figure represents the obtained CV and LSV plot of glassy carbon/LSCO modified electrode which demonstrates the OER onset to be 1.47 V (black trace), which is also confirmed by the current response and appearance of bubbles on the electrode surface. Current density and onset potential are important indicators to evaluate the efficacy of the electrocatalyst. In presence of 0.5 M MeOH along with 0.5 M KOH, higher current density and low overpotential (red trace) were observed indicating that the catalyst has activity towards methanol electrooxidation.
