Synthesis of new mesostructured aluminophosphates

Two mesolamellar aluminophosphates, designated L1 and L2, were synthesised by supramolecular templating from solutions containing a cationic surfactant. Optimal synthesis conditions have been established. XRD diffraction, solid-state NMR, FTIR, thermogravimetry and SEM reveal structural differences between the two materials. The synthesis of L2 requires higher temperatures than for L1 and involves an induction period.
