Synthesis and characterization of large single crystal of ZAPSO-43
چکیده انگلیسی


• Large single crystals of GIS were synthesized by using DPA as organic template.
• The quality and size of GIS are sensitive to crystallization conditions.
• Molar Si/Al ratio has a pronounced effect on the size and structure of crystals.
• Molar Zn/Al ratio also has a pronounced effect on the size and structure of crystals.
• High HF content is favor to the synthesis of large single crystals.

We investigated the effects of gel composition and crystallization conditions on the hydrothermal synthesis of ZAPSO-43 single crystals in detail. Large single crystals of ZAPSO-43 (around 250 μm) with high quality were synthesized by optimizing the following synthesis conditions: crystallization temperature and duration, molar ratio of SiO2/Al2O3 and ZnO/Al2O3, content of HF acid and organic template dipropylamine (DPA). Single-crystal X-ray diffraction measurement show that the as-synthesized ZAPSO-43 are of Fddd symmetry with lattice constants a = 9.9985 Å, b = 14.2565 Å and c = 14.5726 Å, α = β = γ = 90° and their unit volume is V = 2077.22 Å3.
