Synthesis of large optically clear SAPO-47 single crystals using n-Propylamine (cas 107-10-8) as template

Add time:08/26/2019    Source:sciencedirect.com

We report the hydrothermal synthesis of SAPO-47 crystals by using n-propylamine (NPA) as template. The resulting product sensitively depends on the gel compositions and synthesis procedure. By optimizing the molar ratio of SiO2/Al2O3, content of HF and NPA, large perfect cubic-shaped SAPO-47 crystals are obtained (size 260 µm×260 µm), at a synthesis temperature of 200 °C with a crystallization of 50 h.
