Isomorphous substitution induced ionothermal synthesis of magnesium aluminophosphate zeolites in fluoride-free media†
Abstract
Magnesium aluminophosphate zeolites (MgAPOs) with AEL, AFI and ATS structures were ionothermally synthesized in a fluoride-free system depending on the structure of the ionic liquids and the concentration of magnesium, where the incorporation of magnesium into the framework induced their crystallization, resembling that of fluoride ion in aluminophosphate analogues formation.
