Autor: Evert J. Ditzel, Justin S. J. Hargreaves, Stephen Sproules, Nicholas A. Spencer

Publikováno v: Journal of Materials Chemistry A. 4:7036-7044

It is shown that control of the degree of coking can lead to the observation of hyperfine structures in the carbonaceous residues deposited from methanol over mordenite (H-MOR) at temperatures relevant to the conversion of methanol to hydrocarbons. E

Publikováno v: Journal of Cluster Science. 17:27-45

Reaction of CO with hydrogen in the presence of [Ru3(CO)12], KI and N-methylpyrrolidone produces small amounts of methanol under mild conditions. Using D2 the methanol is CD3OD confirming that it is a product of CO hydrogenation. In the presence of a
