Sulfur-Doped Fe/N/C Nanosheets as Highly Efficient Electrocatalysts for Oxygen Reduction Reaction
Abstract
The high-temperature pyrolyzed Fe/N/C is one of the tremendous potential nonprecious metal electrocatalysts for oxygen reduction reaction (ORR). Metal-free carbon materials doped with heteroatoms have also demonstrated prominent electrocatalytic performance for ORR. The previous work of S-doping Fe/N/C was produced by pyrolyzing melamine and iron thiocyanate, in which S was from iron thiocyanate. Here, for the first time, we realized an in situ S-doping in Fe/N/C (denoted as S-Fe/N/C) electrocatalyst with S doping reaching 4.76 at % by pyrolyzing thiourea as the S source and iron acetate showing high-performance ORR activity in both alkaline and acid solution. The catalyst pyrolyzed at 700 °C and the mass ratio 1:0.2 shows the best activity for ORR. The optimal catalyst displays much greater durability and higher tolerance to methanol than Pt/C (20 wt %). Results of electrochemical measurements show that the S-Fe/N/C follows 4e pathway in alkaline and acid conditions.

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.
