Silicoaluminophosphate-11 (SAPO-11) molecular sieves synthesized via a grinding synthesis method

Abstract

Aluminophosphate molecular sieves with an AEL-type structure and various framework compositions were prepared via a grinding synthesis method (GSM). The rapid crystal growth rate was due to the enhanced interactions between the templates and aluminum species and abundant low-polymerized phosphorus species. The amount of template and water used was substantially reduced, which has a great economic and environment impact for large-scale synthesis.
