Journal ArticleDOI
Molybdenum carbide catalysts. I. Synthesis of unsupported powders
TL;DR: In this article, a temperature-programmed reaction between MoO3 of low specific surface area Sg and a CH 4 H 2 mixture produces unsupported powders of hexagonal Mo2C with Sg from 50 to 100 m2 g− and CO uptake number density of up to 5.0 × 1014 cm−2.
Journal ArticleDOI
Oxidative Coupling of Methane to Higher Hydrocarbons
J. S. Lee,S. T. Oyama +1 more
TL;DR: In this paper, a possible route is oxidative dimerization of methane followed by oligomerization of the C2 products, which can be used as feedstock for the production of chemicals or liquid fuels.
Journal ArticleDOI
Molybdenum carbide catalysts: II. Topotactic synthesis of unsupported powders
TL;DR: In this article, a temperature-programmed reaction (TPR) of MoO 3 with ammonia producing first Mo 2 N which was subsequently converted to α-MoC 1− x by TPR with a CH 4 /H 2 mixture.
Journal ArticleDOI
Hydrodesulfurization of thiophene over unsupported molybdenum carbide
J. S. Lee,M. Boudart +1 more
TL;DR: In this paper, the results of thiophene HDS over unsupported molybdenum carbide were compared to those obtained on a presulfided Mo/Al 2 O 3 catalyst.
Journal ArticleDOI
Interaction of pyridine and ammonia with a sulfate-promoted iron oxide catalyst
J. S. Lee,Doo S. Park +1 more
TL;DR: In this article, sulfate-promoted iron oxide with pyridine or ammonia was investigated by means of infrared spectroscopy and temperature-programmed desorption/reaction coupled with mass spectrometry.
