Enantiomerically enriched, polycrystalline molecular sieves.
Zeolite and zeolite-like molecular sieves are being used in a large number of applications such as adsorption and catalysis. Achievement of the long-standing goal of creating a chiral, polycrystalline molecular sieve with bulk enantioenrichment would enable these materials to perform enantioselective functions. Here, we report the synthesis of enantiomerically enriched samples of a molecular si...
متن کاملIncorporation of [Fe(bipy)Cl4][bipy.H] in molecular sieves: a “ship in a bottle synthesis” approach
Incorporation of [Fe(bipy)Cl4][bipy.H] (1) (where bipy is 2,2′-bipyridine) in the molecular sieves of the type LTA, NaY and mesoporous Al-MCM-41 by using a “ship in a bottle synthesis” approach was investigated. [Fe(bipy)Cl4][bipy.H] was successfullyincorporated in the channels ofmesoporousAl-MCM-41, and the product was characterized by X-ray diffraction, FTIR and BET analysis. It was fou...
متن کاملProgress in heteroatom - containing aluminophosphate molecular sieves
Over the past 30 years, heteroatom-containing aluminophosphate molecular sieves as a prime class of heterogeneous single-site solid catalysts have been quickly developed since the first discovery of aluminophosphate molecular sieves in 1982, and a large variety of such materials with 48 unique zeotype structures have been prepared. This work mainly presents the progress in the development of he...
متن کاملIonothermal 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. ...
متن کاملCarbon Molecular Sieves – A kinetic study
Carbon Molecular Sieves (CMS) are unique materials which are widely used in processes based on pressure swing adsorption (PSA) for nitrogen generation by oxygen removal from air [1, 2, 3] and for the enrichment of methane from biogas or landfill gas [4]. Steadily improved CMS were launched in the last years to cover these applications. The recent materials are characterized by higher sorption c...
