Abstract

Abstract: CoAPO-11 molecular sieve with a high crystallinity was prepared by hydro thermal syn thesis from a non-aqueous system(EG) in the presence of Et₂NH or i-Pr₂NH as a structuredirecting agent. The X-ray diffraction(XRD) patterns, scanning electron micrographs(SEM) revealed that the product powder was pure, homogenous in particle-size. The X-ray powder diffraction data, compositional analysis, thermal stability analysis, UV-V is diffuse reflectance spectroscopic analysis showed that Co(Ⅱ) ions were incorporated in the aluminophosphate framework, tetrahedrally coordinated in the lattice of asprepared samples.

Key words: Hydro thermal syn thesis, CoAPO-11, Non-aqueous system, Molecular sieve
