In Situ1H MAS NMR Spectroscopic Observation of Proton Species on a Mo-Modified HZSM-5 Zeolite Catalyst for the Dehydroaromatization of Methane

The NMR analysis of high-temperature reactions, even at temperatures over 800 K, has been carried out with the aid of a specially designed apparatus. The reaction studied was the catalytic methane aromatization on a molybdenum-modified ZSM-5 catalyst. The experiments could be performed under conditions identical to those used in the real catalytic process.
