Exploration of heteroatom doping in modulating the two-electron selectivity of M–N–C catalysts for the oxygen reduction reaction

Developing efficient electrocatalysts for hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) electrosynthesis is of paramount importance in sustainable chemistry. Herein, we identify a pyrrole-type NiN<sub>3</sub>C<sub>1</sub> configuration as an optimal candidate that exhibits a negligible 0.02 V overpotential, where the unique pyrrole coordination facilitates proximal oxygen protonation to suppress O-O bond cleavage and enhance 2e<sup>-</sup> selectivity.

Abstract

Developing efficient electrocatalysts for hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) electrosynthesis is of paramount importance in sustainable chemistry. Herein, we identify a pyrrole-type NiN<sub>3</sub>C<sub>1</sub> configuration as an optimal candidate that exhibits a negligible 0.02 V overpotential, where the unique pyrrole coordination facilitates proximal oxygen protonation to suppress O-O bond cleavage and enhance 2e<sup>-</sup> selectivity.
