Abstract:

In the presence of N-methyl-1,3-diaminopropane, a new microporous aluminophosphate compound [C4N2H14]2+[H2Al3P3O14]2-(1) was synthesized under hydrothermal condition. Single-crystal X-ray diffraction structural analysis showed that compound 1 crystallizes in the orthorhombic space group Pbca with a=1.59839(11) nm, b=0.99402(6) nm, c=1.82261(11) nm, V=2.8958(3) nm3. Its framework consists of AlO5/AlO6 and PO4 units forming 10-ring channels along [010] direction, where the templates exists. Compound 1 transformed to AlPO4-25(ATV) upon calcination at 550℃. It was further characterized by powder X-ray diffraction(PXRD), inductively coupled plasma(ICP) analysis, scanning electron microscopy(SEM), thermal gravimetric(TG) analysis, and elemental analysis.
