文摘

The crystal size and shape of the silicoaluminophosphate molecular sieve SAPO-34 have been effectively controlled in the reaction system of Al2O3–P2O5–SiO2–TEAOH–H2O under microwave radiations. Nano sheet-like SAPO-34 crystals are obtained when using colloidal silica as the silica source. When TEOS is used as the source of silica, homogeneous SAPO-34 crystals with a particle size of about 100?nm are formed, and the morphology of the crystals changes from uniform nano particles (~100?nm) to microspheres (~1.5?μm) by varying the H2O/Al2O3 molar ratio. To further investigate the morphology control of SAPO-34, the synthetic factors, such as the silica source, water content, crystallization time and aging time have been studied in detail.
