A modulated electronic state strategy designed to integrate active HER and OER components as hybrid heterostructures for efficient overall water splitting
Abstract
Abstract Herein, we report a rational design of one-dimension (1D) porous hybrid heterostructures with the active HER (Mo2C) and OER (Co4S3) embedded N and S co-doped carbon (Co4S3/Mo2 C-N SC) for the effective overall water splitting. Spectroscopic characterizations reveals that modulated electronic state behaviors are generated by the strong chemical couplings at the nanointerface which triggers the charge from Co2+ to Mo4+/Mo6+ through the interfacial Mo-S-Co bond, resulting in producing the considerable amounts of the active sites (i.e., Co3+, Mo2+, and Mo3+) for the HER and OER in the hybrid heterostructures. Interestingly, Co4S3/Mo2 C-N SC shows pronounced synergistic effects in electrocatalytic activity for the HER and OER. When Co4S3/Mo2 C-N SC is used as both anode and cathode for overall water splitting, a low cell voltage of 1.62 eV is generated at 10 mA cm−2. The interesting work highlights the significance of optimization electronic structure based on transition metal-based bifunctional electrocatalysts for the HER and OER.

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.
