A Pentagonal Defect-Rich Metal-Free Carbon Electrocatalyst for Boosting Acidic O2 Reduction to H2O2 Production
Abstract
Metal-free carbon-based materials are considered one of the most promising two-electron oxygen reduction reaction (2e – ORR) electrocatalysts for the green synthesis of hydrogen peroxide (H 2 O 2 ). However, most reported carbon electrocatalysts perform much more effectively in alkalis than in acids. Herein, by creatively using fullerene (C 60 ) as the precursor subject to ammonia treatment, we designed and synthesized a pentagonal defect-rich nitrogen-doped carbon nanomaterial (PD/N–C). It achieves outstanding ORR activity, 2e – selectivity, and stability in acidic electrolytes, surpassing the benchmark PtHg 4 alloy catalyst. Impressively, the flow cell based on the PD/N–C catalyst achieves nearly 100% Faraday efficiency with a remarkable H 2 O 2 yield, representing the best improvement among all the metal-free catalysts. Experimental and theoretical results reveal that such superb 2e – ORR performance of PD/N–C originates from the synergism between pentagonal defects and nitrogen dopants. This work presents an effective strategy for the design and construction of highly efficient acid-resistant carbon electrocatalysts for H 2 O 2 production and beyond.

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.
