Single-Atom Co–N4 Electrocatalyst Enabling Four-Electron Oxygen Reduction with Enhanced Hydrogen Peroxide Tolerance for Selective Sensing
Abstract
Electrocatalysis of the four-electron oxygen reduction reaction (ORR) provides a promising approach for energy conversion, storage, and oxygen monitoring. However, it is always accompanied by the reduction of hydrogen peroxide (H 2 O 2 ) on most employed catalysts, which brings down the electrocatalytic selectivity. Here, we report a single-atom Co–N 4 electrocatalyst for the four-electron ORR at an onset potential of 0.68 V (vs RHE) in neutral media while with high H 2 O 2 tolerance, outperforming commercial Pt electrocatalysts. Electrochemical kinetic analysis confirms that the Co–N 4 catalytic sites dominantly promote the direct four-electron pathway of the ORR rather than the two sequential two-electron reduction pathways with H 2 O 2 as the intermediate. Density functional theory calculations reveal that H 2 O 2 reduction is hampered by the weak adsorption of H 2 O 2 on the porphyrin-like Co centers. This endows the electrocatalyst with improved resistance to current interference from H 2 O 2, enabling highly selective O 2 sensing as validated by the reliable sensing performance in vivo. Our study demonstrates the intriguing advantage of single-atom catalysts with high capacity for tailoring metal–adsorbate interactions, broadening their applications in environmental and life monitoring.

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.
