In catalytic pyrolysis of PP with Fe-Ni bimetallic catalysts, 700 °C is the critical threshold for CNT growth; below this temperature, inferior products dominated by amorphous carbon are formed.
“They further investigated the effect of different catalytic temperatures, identifying 700 °C as the critical threshold for CNT growth; below this temperature, inferior products dominated by amorphous carbon were formed.”

Within 700-800 °C, directional CNT growth is observed; increasing temperature beyond this range produces only a marginal increase in yield without substantially altering the 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.
