Abstract:

In the organotemplate-free system, a layered aluminophosphate Na4[Al4P4O18]·H2O(1) was synthesized with Na+ ion as the structure-directing agent under hydrothermal condition. The structure was determined by single-crystal X-ray diffraction, and further characterized by powder X-ray diffraction(PXRD), scanning electron microscopy(SEM), inductively coupled plasma(ICP) and thermal gravimetric(TG) analyses. Compound 1 crystallizes in the monoclinic space group P21/c with a=1.00887(9) nm, b=0.86747(8) nm, c=0.97580(9) nm, V=0.77387(12) nm3, and Z=2, and its framework consists of AlO5 and PO4 units. Compound 1 possesses high thermal stability, and the crystal structure remains unchanged after calcination at 400 ℃ in air. The proton conductivity measurement gives that compound 1 possesses excellent conductivity with σ the value of 1.19×10-3 S/cm when immersed in water at 55 ℃, which is higher than those of traditional zeolitic materials.
