Synthesis and structure solution of small pore aluminophosphates
Abstract
By utilising template molecules known to produce Zeotype framework materials, two new synthesis routes leading to the production of DAF-4 and DAF-5 were presented. To reproduce the microporous material DAF-4 the template molecule successful in the synthesis of the pure SiO2 structural analogue, LEV, was used and produced the phase pure material DAF-4. To reproduce the DAF-5 microporous material, the template used was chosen for its shape, which closely matched that used previously, differing only in the nitrogen atom positions. A phase pure sample of DAF-5 was produced.
