In order to corroborate that oxidation current is indeed due to methanol oxidation, quantitative analysis of the product gases resulting from CA experiment (1.54 V for 1800 s) is carried out in Gas Chromatograph. During the CA experiment the gases sampled in the head space of the closed electrochemical cell (1 ml of gas was taken) were collected and subjected to gas chromatography. It is evident from Figure that on addition of methanol, OER enhances from 460 nano moles/ml to 840 nano moles/ml. Thus, in presence of methanol rate of OER increases to almost double confirming the assisted OER in presence of methanol electrooxidation.
