Autor: Johan A. Martens, and Pierre A. Jacobs, Anton-Jan Bons, Raman Ravishankar, Wilfried Mortier, Machteld M. Mertens, Christine E. A. Kirschhock

Publikováno v: Chemistry of Materials. 17:5618-5624

In this paper we propose a structure for the novel zeolite material COK-5. COK-5 has a distinct X-ray diffraction pattern, showing unique peaks and broad features. This suggests a layered structure with stacking disorder, consistent with SEM and TEM

Comparing homogeneous and heterogeneous acid catalysts by a density-functional based sensitivity analysis of their interaction with carbenium ions

Autor: Bart G. Baekelandt, Vladimir B. Kazansky, Wilfried Mortier, Jan L. Lievens

Publikováno v: Journal of Molecular Catalysis. 83:135-143

An attempt has been made to develop a quantitative comparison of the properties of homogeneous and heterogeneous catalyst systems. The bond formation, and its projected covalent character, of a carbenium ion with the surface of zeolites and with wate

Cation site energies in dehydrated KFI-type zeolites: d-NaKFI, d-NaHKFI, and d-KKFI

Autor: Wilfried Mortier, Jan L. Lievens, Johnannes P. Verduijn

Publikováno v: Zeolites. 12:690-697

The Na- and K-ion distribution in dehydrated KFI-type zeolites ( Si Ai = 3.3) was used as a probe for the computation of the site-energy differences at the hexagonal prism, the puckered (Na and K), and flat eight-rings (K only) using an (exact) stati

Influence of the framework composition on the cation-site energy: the structures of dehydrated NaxHGaY (x = 54, 36, and 21) zeolites

Autor: Wilfried Mortier, Johannes Petrus Verduijn, Jan L. Lievens

Publikováno v: The Journal of Physical Chemistry. 96:5473-5477

Using X-ray powder diffraction, the structure and distribution of the exchangeable cations of dehydrated Na{sub x}HGaY (x = 54, 36,and 21) was determined and compared to Na in dehydrated (Al)Y. From this, it is concluded that the substitution of Al b

Journal of Physical Chemistry B, American Chemical Society, 2003, 107 (40), pp.11065-11071. ⟨10.1021/jp0223760⟩

International audience; The adsorption behavior of the butene isomers on NaY zeolite is studied experimentally and compared with quantum chemical predictions. The adsorption experiments were carried out with the pulse chromatographic method, the calc
