Abstract:

A rapid synthetic strategy through ball milling and recrystallization was successfully developed. Aluminophosphate molecular sieve with AWO topology was prepared by the precursor of two-dimensional(2D) layered aluminophosphate AlPO-IM. Simultaneously, metal-containing aluminophosphate molecular sieves with LAU topology were synthesized by introducing the metal heteroatoms in the ball-milling process. The phase transformation mechanism was comprehensively analyzed by Raman spectroscopy and CShM calculation. The results show that metal heteroatoms have an inorganic structure-directing effect in the synthesis of LAU molecular sieves. The ball milling-recrystallization method not only greatly shortens the crystallization time, but also converts the 2D layered aluminophosphates into a 3D molecular sieve under solvent-free conditions. Compared with the traditional hydrothermal/solvothermal synthesis, the ball milling-recrystallization method has the characteristics of high efficiency and energy saving, which expands the synthetic route of aluminophosphate molecular sieves.
