摘要：
SAPO-11 samples have been synthesized by the conventional route and from an aqueous solution containing F- anions. Characterization of these samples by X-ray diffraction (XRD), chemical analysis, X-ray photoelectron spectroscopy (XPS), thermal analysis, NMR, adsorption measurements and catalytic test reaction reveals that the samples are highly crystalline, but differ in some physico-chemical properties. These differences in the properties of SAPO-11 obtained via different synthesis routes are correlated with different ordering of silicon substitution within the framework.
