How Nitrogen-Doped Graphene Quantum Dots Catalyze Electroreduction of CO2 to Hydrocarbons and Oxygenates
Abstract
Recently, metal-free nitrogen-doped graphene quantum dots (NGQDs) have been experimentally demonstrated to electrochemically convert CO 2 into high-order hydrocarbons and oxygenates, after more than 30 years since the identification of copper as an active metal catalyst for such conversions. However, the physicochemical principle of such catalytic activity for NGQDs has remained unclear. Here, by performing first-principles simulations, we have systematically investigated the underlying mechanisms governing the whole process. The introduction of N atoms into edges of graphene quantum dots enhances their bonding with *COOH, effectively promoting the reduction of CO 2 to CO. By including the influences of water, we reveal that the selective production of CH 4 over CH 3 OH is attributed to a much lower kinetic barrier for the conversion of adsorbed *CH 2 OH to *CH 2 via water molecule mediated proton shuttling. Further, adsorbed *CH 2 provides active sites for the coupling with CO to generate C 2 products, including both C 2 H 4 and C 2 H 5 OH. These results offer theoretical insights into the reduction pathways of CO 2 on NGQDs, which may facilitate the design of metal-free carbon-based catalysts for efficient CO 2 reduction.

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.
