SAPO-34 molecular sieves with different Si coordination environment were synthesized by adjusting SiO 2 /Al 2 O 3 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
