WebA novel interzeolite transformation strategy using internally confined organic structure directing agents (OSDAs), called the “OSDA-confined” strategy, is proposed for highly crystalline nanosized high-silica ZSM-5 zeolite synthesis, by which high yield and fast synthesis of ZSM-5 is achieved using BEA zeolite as a raw material. WebZeolites are natural, microporous minerals, commonly used as catalysts and absorbance material due to their high cation exchange capacity (Na +, K +, Ca 2+, Mg 2+ ). Zeolites can be also synthesized chemically in large scale. This allows the modification of the chemical characteristics and enlarges the scope of application.
Some of the more common mineral zeolites are analcime, chabazite, clinoptilolite, heulandite, natrolite, phillipsite, and stilbite. An example of the mineral formula of a zeolite is: Na2Al2Si3O10·2H2O, the formula for natrolite.
