A Self‐Standing High‐Performance Hydrogen Evolution Electrode with Nanostructured NiCo2O4/CuS Heterostructures
Abstract
An efficient self‐standing 3D hydrogen evolution cathode has been developed by coating nickel cobaltite (NiCo 2 O 4)/CuS nanowire heterostructures on a carbon fiber paper (CFP). The obtained CFP/NiCo 2 O 4/CuS electrode shows exceptional hydrogen evolution reaction (HER) performance and excellent durability in acidic conditions. Remarkably, as an integrated 3D hydrogen‐evolving cathode operating in acidic electrolytes, CFP/NiCo 2 O 4/CuS maintains its activity more than 50 h and exhibits an onset overpotential of 31.1 mV, an exchange current density of 0.246 mA cm−2, and a Tafel slope of 41 mV dec−1. Compared to other non‐Pt electrocatalysts reported to date, CFP/NiCo 2 O 4/CuS exhibits the highest HER activity and can be used in HER to produce H 2 with nearly quantitative faradaic yield in acidic aqueous media with stable activity. Furthermore, by using CFP/NiCo 2 O 4/CuS as a self‐standing electrode in a water electrolyzer, a current density of 18 mA cm−2 can be achieved at a voltage of 1.5 V which can be driven by a single‐cell battery. This strategy provides an effective, durable, and non‐Pt electrode for water splitting and hydrogen generation.

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.
