Engineering Sulfur Defects, Atomic Thickness, and Porous Structures into Cobalt Sulfide Nanosheets for Efficient Electrocatalytic Alkaline Hydrogen Evolution
Abstract
The development of nonprecious metal-based electrocatalysts with high mass activity and efficient atom utilization for alkali hydrogen evolution reaction (HER) is of great importance for the preparation of hydrogen resource. The combination of ultrathin and porous structure, especially with the assistance of vacancy, is expected to be beneficial for achievement of high mass activity, but the development of a facile, robust, and generalized strategy to engineer ultrathin, porous, and vacancy-rich structure into nonlayer structured transition metal-based electrocatalysts is highly challenging. Here, we propose a plasma-induced dry exfoliation method to prepare nonlayer structured Co 3 S 4 ultrathin porous nanosheets with abundant sulfur vacancies (Co 3 S 4 PNS vac ), which show an onset overpotential of only 18 mV and an extremely large mass activity of 1056.6 A g –1 at an overpotential of 200 mV. Experimental results and theoretical calculations confirm that the efficient alkaline HER performance could be attributed to the abundant active sites, good intrinsic activity, and accelerated electron/mass transfer. Additionally, the plasma-assisted conversion method can also be extended to fabricate CoSe 2 and NiSe 2 ultrathin porous nanosheets with selenium vacancies.

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.
