(author), Hensen, Emiel (author), Kapteijn, F. (author), Gascon, Jorge (author)The active sites on the methane dehydroaromatization (MDA) catalyst Mo/HZSM-5 are very hard to characterize, because they are present in various geometries and sizes and only form under reaction conditions with methane at 700 °C. To address these issues an experimental strategy is presented that enables distinguishing different active sites...journal article 2019

Vollmer, I. (author), Li, G. (author), Yarulina, I. (author), Kosinov, N. (author), Hensen, Emiel J. (author), Houben, Klaartje (author), Mance, Deni (author), Baldus, Marc (author), Gascon, Jorge (author), Kapteijn, F. (author)Although the local geometry of Mo in Mo/HZSM-5 has been characterized before, we present a systematic way to manipulate the configuration of Mo and link it to its catalytic properties. The location and geometry of cationic Mo-complexes, the precursor of the active metal site for methane dehydroaromatization, are altered by directing the way...journal article 2018

Kosinov, Nikolay (author), Coumans, Ferdy J A G (author), Uslamin, Evgeny (author), Kapteijn, F. (author), Hensen, Emiel J M (author)Non-oxidative methane dehydroaromatization is a promising reaction to directly convert natural gas into aromatic hydrocarbons and hydrogen. Commercialization of this technology is hampered by rapid catalyst deactivation because of coking. A novel approach is presented involving selective oxidation of coke during methane dehydroaromatization...journal article 2016

(author), Gascon, Jorge (author), Kapteijn, F. (author), Hensen, Emiel J M (author)In applying a multi-scale spectroscopic and computational approach, we demonstrate that the synthesis of stacked zeolite silicalite-1 nanosheets, in the presence of a long-tail diquaternary ammonium salt surfactant, proceeds through a pre-organised phase in the condensed state. In situ small-angle X-ray scattering, coupled to paracrystalline...journal article 2016
