Effect of water on the ionothermal synthesis of molecular sieves.

Ionothermal synthesis of aluminophosphate molecular sieves

Effects of ionic liquid structures on the aluminophosphate molecular sieve products in ionothermal synthesis process were investigated. The results showed that the possible structure-directing effect of ionic liquid might exist during ionothermal synthesis. Microwave heating was introduced into the ionothermal synthesis, which led to a fast and safe process for preparation of molecular sieves. ...

Structure-directing role of amines in the ionothermal synthesis.

The structure-directing effect of amine has been observed in the ionothermal synthesis of aluminophosphate molecular sieves in 1-butyl-3-methylimidazolium bromide ionic liquid. The seven different amines we tested have an influence on the crystallization dynamics and the final product, leading to the formation of pure AFI and ATV structures.

Ionothermal synthesis of aluminophosphate molecular sieve membranes through substrate surface conversion.

Applications of zeolite membranes in separation, chemical sensors, and catalytic membrane reactors have led to extensive studies on their fabrication. To date, mainly silicatebased zeolite membranes of the structure types MFI, DDR, LTA, and FAU have been synthesized on different substrates and evaluated for singleor multiple-gas permeation. Routes for the synthesis of zeolite membranes can be b...

Mixed template effect adjusted by amine concentration in ionothermal synthesis of molecular sieves.

Cationic templating of imidazolium adjusted by the amine concentration in an ionothermal system results in products with larger channels or cage-like structures by reassembling the inorganic hosts around the changed organic guests.
