Long-chain hydrocarbons by CO2 electroreduction using polarized nickel catalysts
Open accessAbstract
The electroreduction of CO2, driven by renewable electricity, can be used to sustainably generate synthetic fuels. So far, only copper-based materials have been used to catalyse the formation of multicarbon products, albeit limited to C2 or C3 molecules. Herein, we disclose that inorganic nickel oxygenate-derived electrocatalysts can generate linear and branched C3 to C6 hydrocarbons with sustained Faradaic efficiencies of up to 6.5%, contrasting with metallic nickel, which is practically inactive. Operando X-ray absorption spectroscopy, electrochemical CO stripping and density functional theory pinpoint the presence of stable, polarized Niδ+ active sites associated with Ni–O bonds, which bind CO moderately. The reduction of selected C1 molecules and density functional theory simulations suggest that the Niδ+ sites promote a mechanism reminiscent of the Fischer–Tropsch synthesis: COOH + CHx coupling followed by successive CHx insertions. Our results disclose atom polarization to be the key that prevents the CO poisoning of nickel and enables CO2 reduction to a wider pool of valuable products. Cu-based catalysts have dominated CO2 electroreduction as a result of their unique ability to produce C2 or C3 products, while Ni has largely been excluded due to poisoning by intermediate CO. Here, inorganic Ni oxygenate-derived electrocatalysts with polarized Ni𝛿+ sites can produce multicarbon products, including C3 to C6 hydrocarbons.

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.
