Precisely Tuning the Number of Fe Atoms in Clusters on N-Doped Carbon toward Acidic Oxygen Reduction Reaction
Open accessAbstract
Summary Atomically dispersed transition metals anchored on N-doped carbon are identified as a class of promising candidates alternatively to Pt-based catalysts for oxygen reduction reaction but still restricted by the low activity and durability in acidic media. Herein, we report a new strategy for precisely tuning the number of Fe atoms in clusters anchored on N-doped carbon. Such a tunability offers the capabilities of altering O2 adsorption from superoxo-like to peroxo-like configuration as well as tailoring N species in carbon matrix during pyrolytic catalyst synthesis. As a result, Fe2 clusters on N-doped carbon display excellent acidic ORR activity with a half-wave potential of 0.78 V versus reversible hydrogen electrode (RHE) as well as remarkable durability with only a −20 mV shift after 20,000 cycles in 0.5 M H2SO4 solution. This work provides insights into non-noble-metal electrocatalyst design at the atomic level from the angle of both active sites and catalyst supports.

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.
