Title: Atomically dispersed manganese catalysts for oxygen reduction in proton-exchange membrane fuel cells

Abstract

Platinum group metal (PGM)-free catalysts that are also Fe-free are highly desirable for the oxygen reduction reaction (ORR) in proton exchange membrane fuel cells, as they avoid possible Fenton reactions. Here we report an efficient ORR catalyst that consists of atomically dispersed nitrogen-coordinated single Mn sites on partially graphitic carbon (Mn-N-C). Evidence for the embedding of the atomically dispersed MnN4 moieties within the carbon surface-exposed basal planes was established by X-ray absorption spectroscopy and their dispersion was confirmed by aberration-corrected electron microscopy with atomic resolution. The Mn-N-C catalyst exhibited a half-wave potential of 0.80 V vs. RHE, approaching that of Fe-N-C catalysts, along with significantly enhanced stability in acidic media. The encouraging performance of the Mn-N-C catalyst as a PGM-free cathode was demonstrated in fuel cell tests. First-principles calculations further support the MnN4 sites as the origin of the ORR activity via a 4e- pathway in acidic media.

Fig. 1 Fig. 1: Schematic diagram of atomically dispersed MnN4 site catalyst synthesis. A two-step doping and adsorption approach can gradually increase the density of the atomically dispersed and nitrogen-coordinated MnN4 sites into the 3D carbon particles. In the first step, Mn-doped ZIF-8 precursors are carbonized and then leached with an acidmore » solution to prepare partially graphitized carbon host with optimal nitrogen doping and microporous structures. In the second step, additional Mn and N sources were adsorbed into the 3D carbon host followed by a thermal activation to generate increased density of MnN4 active sites.« less
