Hydrothermal synthesis of high silica zeolite Y using tetraethylammonium hydroxide as a structure-directing agent

High silica zeolite Y with a SiO2/Al2O3 ratio of 7.76 is successfully synthesized with tetraethylammonium hydroxide (TEAOH) as a structure-directing agent. The high silica zeolite Y shows outstanding high temperature thermal stability and hydrothermal stability.
