Highly active nickel oxide water oxidation catalysts deposited from molecular complexes

Abstract

Nickel oxide (NiOx) water oxidation catalysts with high catalytic activity have been electrodeposited from [Ni(en)3]Cl2 (en = 1,2-diaminoethane, NiOx-en) in a 0.10 M borate buffer (NaBi) solution (pH = 9.2). Electrolysis experiments at a fixed applied potential of 1.1 V (vs. Ag/AgCl) established that the NiOx-en films sustain a stable current of 1.8 mA cm−2 for extended periods, compared with 1.2 mA cm−2 for films derived from [Ni(OH2)6](NO3)2 and [Ni(NH3)6]Cl2 when tested in a 0.60 M NaBi buffer. XAS studies indicate that the γ-NiOOH phase is formed in each case whereas SEM studies revealed significant differences in film morphology. The NiOx-en films were found to be more homogenous and to have a higher electroactive surface area, as determined from capacitance measurements. The results highlight the influence that the choice of molecular precursor can have on the activity and robustness of electrodeposited NiOx water oxidation 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.
