Single step electrochemical semi-exfoliated S-doped graphene-like structures from commercial carbon fiber as efficient metal-free catalyst for hydrogen evolution reaction
Abstract
The hydrogen evolution reaction (HER) is the core of electrocatalysis and plays a crucial role in water splitting to obtain hydrogen. It has been inevitable to develop metal‐free catalysts in terms of sustainability, the environment, and economic feasibility. Carbon‐based materials are called metal‐free electrocatalysts and are regarded as one of the most promising candidates due to their abundant source, but they often show poor activity. The strategic aim of this study is to convert commercial carbon fiber into heteroatom‐doped graphene‐like surfaced fibers via an eco‐friendly and fast intercalation/semi‐exfoliation mechanism called Yucel's method. Furthermore, X‐ray photoelectron spectroscopy (XPS) verified that the intercalation has successfully taken place and that the heteroatoms (S, O) are connected to the graphene‐like structure by covalent bonds. The catalysts with 1 M H2SO4 showed superior HER performance compared to bare CF.

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.
