Figure a). is the LSV curve plot of the catalyst for ethanol oxidation reaction (1 M KOH + 1 M Ethanol, scan rate 50 mV/s), Figure b). is the log J vs. potential plot of the LSV curve in Figure a)., and Figure c). is the CV curve for the same sample with scan rate 200 mV/s. How can I get an accurate tafel slope value of EOR and what part can I take from the log J vs. potential?
