Further Studies on Aluminophosphate Molecular Sieves Part 1 . - AIPO , - HS : A Hydrated Aluminophosphate Molecular Sieve
Pure, highly crystalline AIPO,-H2 is synthesized from an aluminophosphate gel containing dipentylamine and characterized using X-ray diffraction, Fourier-transform infrared spectroscopy, scanning electron microscopy, thermogravimetry and solid-state nuclear magnetic reson!nce spectroscopy. The AIPO,-H2 structure has orthorhombic symmetry with cell parameters of a = 16.184(5) A, b = 9.914(3) A a...
متن کاملVertical aluminophosphate molecular sieve crystals grown at inorganic-organic interfaces.
Tubular aluminophosphate molecular sieve crystals were grown at an organic interface with their channels (7 angstroms in cross section) vertical to the substrate. To induce surface nucleation and oriented growth of AIPO(4)-5 crystals, organophosphonate layers cross-linked with Zr(IV) were assembled on a gold substrate and the modified substrate was immersed in a hydrothermal bath containing rea...
متن کاملIonothermal 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...
متن کاملIonothermal synthesis of a CHA-type aluminophosphate molecular sieve membrane and its formation mechanism
A gas permeable CHA-type aluminophosphate molecular sieve membrane was ionothermally synthesized on a porous d-alumina substrate through the so-called “substrate surface conversion” method. The synthetic conditions for this specific membrane were optimized. The temperature, time and the amounts of H3PO4 and HF in the initial synthesis solution were investigated. X-ray diffraction (XRD), scannin...
متن کاملSimulation of Alkane Adsorption in the Aluminophosphate Molecular Sieve AlPO4-5
Adsorption isotherms of alkanes ranging from methane through pentane in the microporous aluminophosphate AlPO4-5 are calculated using grand canonical monte carlo simulations. These simulations predict a surprisingly complex behavior. For methane and ethane we find at low temperatures a low-density-high-density transition that resembles capillary condensation. At intermediate temperatures a high...
