Shape Selective Catalysis By Zeolites

Explanation

What are Zeolites?

Zeolites are highly absorbent porous material, composed largely of silica and aluminium mineral. They are used for their capacity to capture and hold a variety of unwanted materials, such as a sponge absorbs water. These aluminosilicate minerals comprise of regular groupings of pores and cavities that can hold a wide variety of cations (positively charged ions), such as Na+ , K+ , Ca2+, as well as small molecules.

Selectivity in Chemical Reactions

One of the key roles of the catalysis is to control the selectivity in chemical reactions. In heterogeneous catalytic reactions in zeolites and zeolite-related microporous solids, this can be accomplished by utilizing the phenomenon of shape-selective catalysis. In an exceptionally simplified way, shape-selective catalysis can be described as the mix of catalysis with the molecular sieve impact.
