When the ORR catalyst i synthesized gives five times greater current density than the commercial Pt/C, then the slope of the KL plot for the catalyst synthesized will be higher because of the higher density. In Kouetcky-Levich equation all the parameters except slope are constant as i used the same electrolyte. So when i calculate number of electrons transferred i am getting wrong answer. Can someone help me with this problem.
It is possible that the ORR catalyzed by your material may not suitable for K-L analysis but 5 times higher current density than Pt/C is interesting. Repeating all of the electrocatalytic measurements is the best way.
i repeated the measurements. I am not able to get the number correct for Pt/C itself. the value is around 5.
