Pristine‐Graphene‐Supported Nitrogen‐Doped Carbon Self‐Assembled from Glucaminium‐Based Ionic Liquids as Metal‐Free Catalyst for Oxygen Evolution

Abstract

For the first time, graphene‐supported N‐doped carbon (G@NC) with a high degree of N doping was synthesized by in situ self‐assembly of a glucaminium‐based ionic liquid on pristine graphene under hydrothermal conditions. This 2D, metal‐free nanohybrid exhibited much higher catalytic activity than most reported metal‐free catalysts for the oxygen evolution reaction (OER) and even state‐of‐the‐art Ir‐ and Ru‐based catalysts because the high content of graphitic N greatly increased the number of OER‐active sites, the pristine graphene significantly promoted the OER activity of the C sites adjacent to the graphitic N atoms, and N‐doped graphitic carbon remarkably enhanced the charge‐transfer rate. This work not only creates a facile and economical approach to controllably fabricate pristine‐graphene‐supported carbon with a high N‐doping level for the development of highly efficient metal‐free OER catalysts but also provides insight into the mechanisms for both the in situ self‐assembly and the high OER catalytic activity of G@NC.

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.
