摘要
SAPO-11 and SAPO-47 crystals have been synthesized using diethylamine (DEA) as the structure-directing agent (SDA) and their morphology have been controlled successfully by varying aging duration. The single crystals were obtained in a short aging duration while film and island-like crystals were obtained in a long aging duration. The effect of SiO2/Al2O3 ration and content of HF on SAPO-47 crystals have been investigated. High molar ration of SiO2/Al2O3 and high content of HF is tend to synthesize larger crystals of SAPO-47. All the samples were characterized by XRD and SEM.
