Amorphous NiWO4 nanoparticles boosting the alkaline hydrogen evolution performance of Ni3S2 electrocatalysts
Abstract
Abstract Heazlewoodite nickel sulfide (Ni3S2) has become attractive for electrocatalytic hydrogen evolution reaction (HER). However, strong sulfur–hydrogen bonds (S–Hads) formed on the surface of Ni3S2 greatly hinder the Hads desorption and reduce HER activity. Herein, amorphous NiWO4 nanoparticles-decorated Ni3S2 electrocatalysts (NiWO4/Ni3S2) have been constructed via a two-step hydrothermal method. The heterostructures exhibit much better HER performance than original Ni3S2 by delivering current densities of −10 and −100 mA cm−2 at low overpotentials of 136 and 274 mV, while those for Ni3S2 are 234 and 424 mV, respectively. Moreover, they display ultra-long stability of 75 h. Theoretical calculation proves the improved activity of NiWO4/Ni3S2 heterostructures is attributed to highly active interfaces between amorphous NiWO4 nanoparticles and Ni3S2 electrocatalysts. The strong electronic interaction between NiWO4 and Ni3S2 decreases the local electron density of Ni and S atoms, facilitates water adsorption on Ni-sites and optimizes hydrogen atom adsorption/desorption on adjacent S-sites with weakened S–Hads.

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.
