High Durability of Fe–N–C Single‐Atom Catalysts with Carbon Vacancies toward the Oxygen Reduction Reaction in Alkaline Media
Open accessAbstract
Single‐atom catalysts (SACs) have attracted extensive interest to catalyze the oxygen reduction reaction (ORR) in fuel cells and metal–air batteries. However, the development of SACs with high selectivity and long‐term stability is a great challenge. In this work, carbon vacancy modified Fe–N–C SACs (Fe H–N–C) are practically designed and synthesized through microenvironment modulation, achieving high‐efficient utilization of active sites and optimization of electronic structures. The Fe H–N–C catalyst exhibits a half‐wave potential (E1/2) of 0.91 V and sufficient durability of 100 000 voltage cycles with 29 mV E1/2 loss. Density functional theory (DFT) calculations confirm that the vacancies around metal–N 4 sites can reduce the adsorption free energy of OH*, and hinder the dissolution of metal center, significantly enhancing the ORR kinetics and stability. Accordingly, Fe H–N–C SACs presented a high‐power density and long‐term stability over 1200 h in rechargeable zinc–air batteries (ZABs). This work will not only guide for developing highly active and stable SACs through rational modulation of metal–N 4 sites, but also provide an insight into the optimization of the electronic structure to boost electrocatalytical performances.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
