Abstract

Glucose was used as a mesoporous structure directing agent to synthesize hierarchical porous silicoaluminophosphate molecular sieves with AEL topology (SAPO-11). Nanosized SAPO-11 with numerous mesopores were confirmed by X-ray diffraction (XRD) and N2 adsorption-desorption analysis. Scanning electron microscopy (SEM) and transimission electron microscopy (TEM) are employed to reveal that inter-crystallinic meso-structures were formed from the aggregation of nanosized crystallites. A proposed mesopore construction mechanism by the addition of glucose is presented based on Energy Dispersive X-ray Spectroscopy (EDS) and CHNS analysis.
