Fig. 5. (a) EIS of pristine MOF-199/, MOF-199/graphene and MOF-199/PANI. (b) Plot comparing the specific capacities of the three different samples calculated from the CV and GCD curves. (c) Specific capacities calculated for pristine MOF-199/, MOF-199/graphene and MOF-199/PANI from CV at various scan rates. (d) Specific capacities calculated from the GCD curves at certain current densities for pristine MOF-199/, MOF-199/graphene and MOF-199/PANI.
