Molecularly well-defined Ni sites at heterogeneous interfaces were derived from the incorporation of Ni<sup>2+</sup> ions into heteroatom-doped graphene. The molecular Ni sites on graphene were redox-active. However, they showed poor activity toward oxygen evolution reaction (OER) in KOH aqueous solution. We demonstrated for the first time that the presence of Fe<sup>3+</sup> ions in the solution could bond at the vicinity of the Ni sites with a distance of 2.7 Å, generating molecularly sized an ...[more]
