Heterogeneous interface engineered atomic configuration on ultrathin Ni(OH)2/Ni3S2 nanoforests for efficient water splitting
Abstract
Abstract The sluggish water dissociation kinetics of low-cost Ni3S2 electrocatalysts severely hinders the hydrogen evolution reaction (HER), resulting in unsatisfied overall water splitting in alkaline media. Herein, we demonstrate the self-assembly of a new nanoforest electrocatalyst by ultrathin Ni(OH)2/Ni3S2 heterogeneous nanosheets (∼1.8 nm) using a high-temperature and large-potential electrodeposition technique. The surface atomic configuration of Ni3S2 is well-modulated by hetero-interface engineering with the Ni(OH)2 cocatalyst, effectively accelerating the Volmer step and OH− adsorption during the HER without sacrificing the oxygen evolution reaction (OER). The resultant electrocatalysts exhibit superior and stable electrocatalytic activity toward the HER and OER in 1 M KOH with small overpotentials of 50 mV and 210 mV at 10 mA cm-2, respectively. Using the Ni(OH)2/Ni3S2 nanoforest as dual-functional electrocatalysts, an alkaline electrolyzer can render 100 mA cm-2 at a very low cell voltage of 1.64 V while keep stable for 120 h at 1.55 V, which outperforms the best report for Ni-based electrocatalysts. This finding gives a new insight into the modulating surface atomic configuration for achieving highly active electrocatalysts for water splitting.

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.
