Abstract

Abstract : Molecular FePc was successfully anchored on a defective mesoporous carbon matrix, which has led to axial charge polarization and promoted the oxygen reduction activity. Abstract : Molecular Fe phthalocyanine (FePc) is successfully anchored on a defective mesoporous carbon framework for the highly efficient oxygen reduction reaction (ORR) with a half-wave potential of 0.86 V ( vs. RHE) and a limited current density of 5.40 mA cm −2 . DFT calculations further suggest that the non-planar structure incorporating FePc can promote charge polarization and decrease the energy barrier.
