Influence of Composition of Nickel‐Iron Nanoparticles for Abiotic CO 2 Conversion to Early Prebiotic Organics
Open accessAbstract
Abiotic synthesis of formate and short hydrocarbons takes place in serpentinizing vents where some members of vent microbial communities live on abiotic formate as their main carbon source. To better understand the catalytic properties of Ni−Fe minerals that naturally exist in hydrothermal vents, we have investigated the ability of synthetic Ni−Fe based nanoparticular solids to catalyze the H 2 ‐dependent reduction of CO 2 , the first step required for the beginning of pre‐biotic chemistry. Mono and bimetallic Ni−Fe nanoparticles with varied Ni‐to‐Fe ratios transform CO 2 and H 2 into intermediates and products of the acetyl‐coenzyme A pathway—formate, acetate, and pyruvate—in mM range under mild hydrothermal conditions. Furthermore, Ni−Fe catalysts converted CO 2 to similar products without molecular H 2 by using water as a hydrogen source. Both CO 2 chemisorption analysis and post‐reaction characterization of materials indicate that Ni and Fe metals play complementary roles for CO 2 fixation.

Vent reactions were promoted by inorganic catalysts, likely including greigite (Fe3S4), magnetite (Fe3O4), and awaruite (Ni3Fe), as well as heteroatoms incorporating Co, Mg, Al, Ca, Ti, and Zr, in the vent flux and microchamber walls.

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.
