High loading single-atom Cu dispersed on graphene for efficient oxygen reduction reaction
Abstract
Abstract Single-atom metal dispersed on graphene materials are highly desired in various fields such as energy conversion/storage, catalysis and nanoelectronics. However, the fabrication of such materials with high loading level is still challenging, as the conventional pyrolysis protocol usually leads to metal agglomeration due to the poor thermal stability of metal precursors and the high surface energy of single-atom metals. Herein, we demonstrate the fabrication of single-atom Cu dispersed on graphene (Cu/G) with ultrahigh Cu loading of 5.4 wt%, using a unique confined self-initiated dispersing protocol. It is revealed that Cu is introduced into graphene matrix via highly active gaseous Cu-containing intermediate, which results in abundant and well-dispersed Cu-containing moieties. This Cu/G material with ultrahigh loading level as an electrocatalyst presents remarkable activity towards the oxygen reduction reaction (ORR) due to the abundant and highly dispersive Cu single atoms, even outperforming the commercial Pt/C. Our findings not only facilitate the development of single-atom metal dispersed on graphene materials but also highlight the importance of tuning active site structures in non-noble metal electrocatalysis.

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.
