Abstract

Single-atom introduced carbon nanomaterials show favorable oxygen-reduction reaction (ORR) and oxygen-evolution reaction (OER) performance for renewable energy applications. Nevertheless, the electronic-structure regulation by decorating heterogeneous single-metal-atoms and the engineering of a single-atom active-sites’ microenvironment need to be optimized simultaneously, which is challenging. Herein, we develop an atomic-interfacial-regulation approach to fabricate dual single Fe/Co atoms synchronized with both nitrogen/sulfur atoms on defective/graphitic/porous carbon nanosheets (Fe,Co/DSA-NSC). The unsymmetrically organized N and S coordinated Fe/Co bridged atomic-sites [Fe-(N 2 S)/Co-(N 2 S) moiety] are established to prompt charge-transfer, lowering the energy barrier of oxygenated reaction-intermediates and leading to boost the reaction-kinetics. As estimated, the Fe,Co/DSA-NSC exhibits an improved ORR/OER activity with higher half-wave potential and lower overpotential ( E 1/2 = 879 mV and η 10 = 210 mV, respectively) and also good cycling stability toward zinc-air batteries. This discovery hence provides a widespread scheme for the synergistic-principles of dual-single-atom catalysts and controlled regulation of an active-sites’ microenvironment toward energy applications.

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.
