Abstract

Abstract NiFe-based compounds have received increasing attention due to their low cost, availability, as well as excellent H2 evolution reaction (HER) and the O2 evolution reaction (OER) catalytic properties. Although it is agreed that the implementation of high activity, the co-existence of Ni and Fe is essential, the identification of active sites and the mechanism of water splitting in NiFe-based compounds have long been controversial. This review focuses on the catalytic centers of NiFe-based oxides/(oxy)hydroxides and related mechanism in alkaline water oxidation process from the perspective of thermodynamics and kinetics. Furthermore, NiFe layered double hydroxides (NiFe LDHs) are introduced separately, emphasizing the necessity of LDH phase formation during water splitting. The review highlights the roles of Fe3+ and the third transition metal Co in NiFe-based catalysts. Finally, a brief perspective on NiFe-based catalysts is proposed. This review will be a good complement to the existing literatures and will contribute to a better study of NiFe-based catalysts.

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.
