In practical applications, stability is a significant index for the durability of an electrocatalyst. Time dependent activity and the stability of perovskite modified electrode is probed by chronoamperometry (CA) measurements. These are evaluated by steady state electrocatalysis at constant applied potential of 1.54 V vs. RHE over 1800 s (Figure ). Chronoamperometry shows a typical response where the current density first rises and drops reaching a steady state within 1800 seconds. After 1800 seconds, the current is ~ 2.0 mA/cm 2 and 5.0 mA/cm 2 for LSCO in 0.5 M KOH and 0.5 M KOH + 0.5 M MeOH contained electrolyte. Steady-state stability tests confirmed that the catalyst remained highly active throughout the prolonged operation of constant potential. Moreover, the stability of the catalyst is tested by characterising via XRD and FESEM. The chronoamperometry test was performed at 1.54 V in the methanol contained KOH electrolyte (Figure ). A comparison between the as synthesised catalyst (Pre) and after electrocatalysis (Post) shows no apparent bulk changes, confirming the stability of the material (Figure ). SEM images shows slight change in morphology as catalyst was exposed to methanol containing electrolyte and as gases evolved during methanol electrooxidation (Figure ). Inductively coupled mass spectrometry (ICP-MS) analysis (Table ) indicated only 0.004% dissolution of all the metal elements (Sr and Co) collectively, which ensured that there is minimal to no element dissolution of catalyst component post electrolysis.
