LSV curves of a Co-N4 and b Co-N4-NP in aqueous 0.050 M H2SO4 solutions and 0.050 M D2SO4/D2O solutions with iR correction at 1600 rpm. c The corresponding kinetic isotope effect against potential. LSV curves of d Co-N4 and e Co-N4-NP in mixed solutions of 0.050 M H2SO4/H2O and 0.050 M D2SO4/D2O with different ratios (n indicates the atom fraction of deuterium of the given solution). f The plots of jn/j0 against n, where n = [D]/([D] + [H]).
