- •
Direct synthesis of mordenite (MOR) zeolite with ultrahigh SiO2/Al2O3 is achieved.
- •
Synthesis is carried out in ionic liquid assisted dry-gel-conversion route.
- •
Tunable SiO2/Al2O3 ranging from 11 to as high as 263 is obtained on MOR zeolites.
- •
Phase transition from MOR to MFI is observed in the synthesis.
- •
The obtained high silica zeolites exhibit high thermal stability.
