  • Carbon nanotubes, whose manufacture frequently requires energy- and resource-intensive production processes, have been produced utilizing waste plastics derived from homopolymers or blends such as polystyrene, polypropylene, and polyethylene.

    “The manufacture of carbon nanotubes, a process that frequently requires energy- and resource-intensive production processes, was conducted, utilizing waste plastics derived from either homopolymers or blends, such as polystyrene, polypropylene, and polyethylene [80,81,82].”

  • Ni-Fe/MCM-41 performance significantly surpassed supports dominated by micropores, such as ZSM-5, Beta, and NKF-5.

    “Its performance significantly surpassed that of supports dominated by micropores, such as ZSM-5, Beta, and NKF-5.”

    From Functional carbon materials from waste plastics: synthesis and applications (2025) · cites this paper as [91]

    The Conclusions (p. unavailable) identify Ni-Fe/MCM41 as producing the highest carbon-deposition yield among the four supports, and Table 2 (p. unavailable) reports 55.6 wt.% versus 50.0, 47.0, and 36.6 wt.% for ZSM5, Beta, and NKF5. Our copy does not establish that all three alternatives are dominated by micropores or report a statistical test supporting 'significantly surpassed.' (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • The superiority of Ni-Fe/MCM-41 is attributed to the high specific surface area of MCM-41 ensuring good dispersion of Ni-Fe alloy particles and providing more active sites, and mesoporous channels enhancing diffusion efficiency of pyrolysis volatiles, whereas large metal particles on Beta promote irregular carbon deposition.

    “This superiority is attributed to the high specific surface area of MCM-41, which ensures good dispersion of Ni-Fe alloy particles and provides more active sites.Meanwhile, the mesoporous channels in Ni-Fe/MCM-41 enhance the diffusion efficiency of pyrolysis volatiles, whereas the large metal particles on Beta promote irregular carbon deposition.”

    Experimental — accuracy not yet measured
  • Ni-Fe/MCM-41 catalyst achieved a record carbon conversion rate of 55.60 wt% in CNT synthesis from waste plastics, benefiting from its hierarchical mesopores.

    “The results showed that the Ni-Fe/MCM-41 system achieved a record carbon conversion rate of 55.60 wt%, benefiting from the advantages of its hierarchical mesopores.”

    From Functional carbon materials from waste plastics: synthesis and applications (2025) · cites this paper as [91]

    Table 2 (page unavailable) reports 55.60 wt% carbon deposition for Ni-Fe/MCM41, the highest among the four catalysts tested. The Conclusions link its high yield to abundant mesopores and high surface area, but do not call the pores hierarchical or the result a record; the reported measure is carbon deposition yield, not a carbon conversion rate. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • CNTs produced using the MCM-41 support exhibit the highest degree of graphitization.

    “Characterization confirmed that CNTs produced using the MCM-41 support exhibit the highest degree of graphitization.”

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.
