Abstract

A novel method for the preparation of iron‐ and nitrogen‐codoped carbon nanotubes (Fe‐N‐CNTs) is proposed, based on the catalytic pyrolysis of waste plastics. First, carbon nanotubes are produced from pyrolysis of plastic waste over Fe‐Al 2 O 3; then, Fe‐CNTs and melamine are heated together in an inert atmosphere. Different co‐pyrolysis temperatures are tested to optimize the electrocatalyst production. A high doping temperature improves the degree of graphite formation and promotes the conversion of nitrogen into a more stable form. Compared with commercial Pt/C, the electrocatalyst obtained from pyrolysis at 850 °C shows remarkable properties, with an onset potential of 0.943 V versus RHE and a half‐wave potential of 0.811 V versus RHE, and even better stability and anti‐poisoning properties. In addition, zinc–air battery tests are performed, and the optimized catalyst exhibits a high maximum power density.

Al2O3-supported Fe catalyst for catalytic pyrolysis of waste plastics produces iron-doped carbon nanotubes (Fe-CNTs) that exhibit excellent performance in the oxygen reduction reaction.
“Cai et al. [88] utilized an Al 2 O 3 -supported Fe catalyst for the catalytic pyrolysis of waste plastics, producing iron-doped carbon nanotubes (Fe-CNTs) that exhibited excellent performance in the oxygen reduction reaction.”
From Functional carbon materials from waste plastics: synthesis and applications (2025) · cites this paper as [88]
The Introduction (p. 3) says alumina loaded with iron was used to produce Fe-CNTs from polypropylene. It then describes a separate co-pyrolysis step with melamine to make Fe-N-CNTs. The remarkable ORR performance is attributed to the resulting Fe-N-CNT850 catalyst, not to the Fe-CNTs alone; the Conclusion (p. 6) reports that Fe-N-CNT850 performed better than pristine Fe-CNT.

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.
