Optimizing the crystallinity and acidity of H-SAPO-34 by flu
发布时间:2021-04-27 22:38
A series of H-SAPO-34 zeolites were synthesized by a hydrothermal method in fluoride media.The as-synthesized H-SAPO-34 zeolites were characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM),N2 physisorption,temperature-programmed desorption of NH3(NH3-TPD) and nuclear magnetic resonance(NMR) measurements.The results showed that a certain concentration of F- anions promoted the nucleation and crystallization of H-SAPO-34.The H-SAPO-34 synthesized...
