Bio-inspired mechanistic insights into CO2 reduction
Abstract
The global energy and environmental concerns related to the excess CO2 concentration in the atmosphere have intensified the research and development regarding CO2 utilization. Due to the high stability and inertness of CO2, CO2 functionalization under mild conditions has been proven to be extremely challenging. Nature has, however, evolved efficient pathways to achieve this difficult transformation. Herein, we compare the mechanisms of CO2 two-electron reduction followed by synthetic catalysts and those by carbon monoxide dehydrogenase and formate dehydrogenase in order to provide more mechanistic insights into future catalyst design.

HCO2- and CO2- anions have very similar bond length, angle and orbital characters.
“Interestingly, HCO 2 -and the CO 2 -anions have very similar bond length, angle and orbitals characters.93”

Angular distortion in the C-O bonds has a direct effect on the energy levels of the HOMO and LUMO orbitals, and there should be an ideal symmetry in the carbonate groups to enable precipitation of magnesite.
“Thus, the angular distortion in the C-O bonds has a direct effect on the energy levels of the HOMO and LUMO orbitals (Fig. 14), [93][94][95] being plausible to assume that there should be an ideal symmetry in the carbonate groups to enable the precipitation of magnesite.”

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.
