An efficient method for the ionothermal synthesis of aluminophospahte with the LTA framework type

Abstract The synthesis of aluminophosphate (AlPO) with the LTA framework type was performed for the first time in 1-butylpyridinium chloride ([C4Py]Cl) which functions as solvent as well as structure-directing agent (SDA). The AlPO-LTA was synthesised only after 2 h of crystallisation time at 160 °C without the addition of a co-SDA. [C4Py]Cl remains intact after synthesis, easily recovered and reused. Thus, an efficient and facile synthesis method for the AlPO-LTA is presented.
