| 英文摘要 | sapo-34 molecular sieves with different si coordination environment were synthesized by adjusting sio2/al2o3 molar ratio in starting gel. the crystal structure, element composition and si coordination environment of the as-synthesized samples were characterized by xrd, sem, xrf and nmr. sapo-34 molecular sieve could be obtained when the sio2/al2o3 molar ratio of the starting gel was higher than 0.075. the content and modeling of si incorporated into sapo-34 framework varied with the sio2/al2o3 molar ratios in the starting gel and different si chemical environments were formed correspondingly. sapo-34 with only si(4al) coordination structure could be prepared when the sio2/al2o3 molar ratio of the starting gel was in range of 0.075-0.15.
