MgO-supported monometallic Fe catalyst in a two-stage pyrolysis-catalysis reactor efficiently converts five plastic polymers (PP, LDPE, HDPE, PS, and PC) into high-quality single-walled carbon nanotubes (SWNTs).
“Using a two-stage pyrolysis-catalysis reactor, they successfully achieved the efficient conversion of five plastic polymers-PP, LDPE, HDPE, PS, and polycarbonate (PC)-into high-quality single-walled carbon nanotubes (SWNTs).”

The catalyst's strong metal-support interaction (SMSI), synergizing with high carbon solubility, maintained the high carbon flux demand from polymer cracking, enabling continuous SWNT growth.

Fe species were highly dispersed on the MgO support surface, and their reducibility provided active sites for CNT growth.
“Catalytic characterization confirmed that Fe species were highly dispersed on the MgO support surface, and their reducibility provided active sites for CNT growth.”

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.
