摘要：
Aluminophosphate gels were synthesized from aluminum isopropoxide, phosphoric acid, and di-n-propylamine. The influence of the synthesis conditions on the characteristics of gel crystallization products (samples of molecular sieve AlPO4-11) was studied using X-ray diffraction analysis, 27Al and 31P MAS NMR spectroscopy, Raman spectroscopy, scanning and transmission electron microscopy, and low-temperature nitrogen adsorption. The morphology of the crystals and secondary pore structure of molecular sieve AlPO4-11 can be controlled by changing the order of mixing of the starting components during synthesis of aluminophosphate gels.
