Hi, does anyone knows why my CV in KOH 1M and EtOH 1M of Palladium in graphene oxide the current forward is lower than the current backward? It should be the opposit, or am i wrong?
In the article the CV for Pd-graphenemic, the Ib was higher than the If but the author didn't write about it.

Hi Luiza,
Usually it depends on your catalyst structure and the molecule you are oxidising. Usually the first scan there is the adsorption of species that requires higher potentials to oxidise, while in the backwards the process is happens in a difference surface since it removed all the adsorbed molecules during the potential scan, and the potential would be different from the forward scan. Is it clear?
