A new addition to the Phillipsite family of molecular sieves: A divalent metal-ion-framework substituted microporous aluminophosphate (DAF-8)

By adding substantial amounts of either Co(II) or Zn(II) salts to a gel composed of Al2O3, P2O5 and the organic template 1,4-diaminocyclohexane, the tendency to yield layered aluminophosphates (AlPOs) is tilted in favour of the production of three-dimensional microporous MAlPOs: in particular, phase-pure samples of a novel Phillipsite structure (designated Davy–Faraday number 8, DAF-8) are formed.
