https://doi.org/10.1007/978-3-030-88634-9ape-selective catalysis can be described as the combination of catalysis with the molecular sieve effect. Shape selectivity effects can occur, if the sizes and shapes of reactants, of products, of transition states or of reaction intermediates are similar to the dimensions of the pores and cavities of the zeolite.

,Characterization of Zeolites — Infrared and Nuclear Magnetic Resonance Spectroscopy and X-Ray Diffrposed to radiation. The quantum mechanical systems absorb (or emit) certain radiation quanta according to certain quantum mechanical transitions. These transitions occur between discrete energy levels which are described by the stationary Schroedinger equation.

Springer Series in Materials Scienceith the biggest consumption being in catalytic cracking and hydrocracking, but ZSM-5, mordenite, and other zeolites have also found commercial application in catalysts. Continuously, new catalytic applications are being developed, or existing ones further fine-tuned, by making use of the many opportunities zeolites offer for tailoring a catalyst.

Modification of Zeolites,amework of zeolites consists of SiO. and AlO. tetrahedra sharing oxygen ions located at their apices, thus resulting in the general framework formula (AlO.).(SiO.)., where n is the number of tetrahedra per unit cell, and x ≤ n/2. Since aluminum is trivalent, every AlO. unit carries a negative charge

A sample, which is built up from quantum mechanical systems (e. g., electrons, nuclei, atoms, molecules), is exposed to radiation. The quantum mechanical systems absorb (or emit) certain radiation quanta according to certain quantum mechanical transitions. Thes
