Siting of Al atoms in the framework T sites, zeolite rings and channel/cavity system, distribution between single close various Al-O-(Si-O)n-Al sequences Si-rich zeolites represent key parameters controlling properties counter ion species. Framework siting is not random or controlled by simple rules depends on conditions synthesis. Al-O-(Si-O)2-Al one 6-MR predominate their population can be varied to a large extent. The dramatically affect catalytic activity/selectivity both protonic...

Ion exchange of Na + ions in a geopolymer by Cs , NH 4 and Co 2+ was used to characterize the accessibility inner volume Na‐geopolymer (Si/Al 1.8) size rings controlling mobility cations matrix. Ultraviolet (UV)—visible (vis) spectroscopy ‐exchanged local geometry regularity shape structures accommodating these Na‐geopolymers exhibit ion‐exchange properties similar those zeolites. All balancing Al atoms network as‐prepared could be replaced (ion‐exchanged) or ions. By analogy zeolites, this...
The effect of several divalent cations (Mn2+, Mg2+, Ni2+, and Co2+) exchanged in Na-ferrierite ammonia adsorption/desorption was studied by FTIR spectroscopy the range 4000−400 cm-1. complete cation exchange eliminated zeolite bridging acidic hydroxyls provided for monitoring stretching bending modes interacting with accompanying parallel changes lattice vibrations induced bare cation−ligand complexes at various coverage. Dehydration ferrierites ion-exchanged gives formation new IR bands...
Shape-selective reactions: Highly selective catalysts are obtained by alkaline and subsequent acid leaching of conventionally prepared zeolites. Active sites that located in the shape-selective environment micropores accessible through mesopores (see picture) provide high selectivity activity acid-catalyzed reactions. As a service to our authors readers, this journal provides supporting information supplied authors. Such materials peer reviewed may be re-organized for online delivery, but...
Highly active and stable inorganic material for dissociation of dioxygen methane oxidation to methanol was developed.
