WebIt is found that the redox potential of the functionalized graphene is sensitive to the types, number, and distribution of oxygen functional groups. First, the carbonyl group … WebGraphene-based nanomaterials can also be functionalized with redox-active molecules which can induce pseudocapacitance and inhibit restacking of the graphene framework. The major criteria in the choice of redox motifs are high solubility, long-term stability, fast reversible redox electron transfer kinetics, and the ability to retain a charge.
