Characterization of Molybdenum Carbides for Methane Reforming by TPR, XRD, and XPS
Abstract
The relationship between various unsupported molybdenum carbides and their activity toward methane reforming at 973 K and 1 atm was studied. Unsupported molybdenum carbides catalyzed the formation of hydrogen in high selectivity, forming ethylene and ethane rather than benzene as the carbon-containing products. η-Mo 3 C 2, which was nitrided at 973 K and subsequently carbided at 1173 K, was more active than both α-MoC 1 - x and β-Mo 2 C in methane decomposition, forming hydrogen in high selectivity. α-MoC 1 - x and γ-Mo 2 N were transformed to η-Mo 3 C 2 in the bulk structure during methane reforming at 973 K. This transformation caused a significant increase in the turnover frequency of methane reforming. η-molybdenum carbide was also formed during CH 4 -TPR of γ-Mo 2 N at 788 K. The linear relationship between the amount of η-carbide determined through H 2 -TPR of the catalysts and the methane disappearance rate revealed that η-Mo 3 C 2 is the active species for methane reforming. From the XPS analysis, Mo 0 was the dominant molybdenum species for the η-Mo 3 C 2 catalysts.

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.
