Supermolecular structure and dynamics of organic molecules adsorbed on the external surface of MGI zeolites. A direct and indirect computational EPR analysis

Article Abstract:

The electron paramagnetic resonance (EPR) providing a spectroscopic method of high sensitivity that is applicable for investigations of the supremolecular structure and dynamics of molecules bound to the external surface of MFI zeolites is demonstrated. Finally, a model was developed, which described the supramolecular structures and dynamics formed by the ketones and MFI zeolites at a function of loading and for the various systems investigated.

Solid-state [super 13]C NMR studies on organic-inorganic hybrid zeolites

Article Abstract:

Solid-state [super 13]C magic angle spinning nuclear magnetic resonance (MAS NMR) is used to study organic-inorganic hybrid zeolite with organic lattice (ZOL). The finding reveals that ZOL is not a physical mixture of a carbon-containing amorphous aggregate and a conventional zeolite but a true organic-inorganic hybrid zeolite.

Water molecules in single file: first-principles studies of one-dimensional water chains in zeolites

Article Abstract:

The water chains in Li-ABW are less stable than those in bikitaite. The stability of such peculiar one-dimensional arrangement is strongly influenced by the zeolite's framework structure.
