A shortcut to high-quality gmelinite through steam-assisted interzeolite transformation

Mechanochemical activation and steam-assisted interzeolite transformation offer a simple, fast cost-efficient synthesis route to gmelinite (GME) zeolite. The use of faujasite (FAU) as the parent zeolite precursor facilitates reaction results in high yields high-quality GME less than 20 h under optimized conditions. accessible porosity amounts stacking-faults were determined by N2 physisorption XRD analysis, respectively. show that quality prepared materials easily competes with zeolites synthesized conventional hydrothermal synthesis, which encourages further research this area. By changing parameters, approach may also be used for production several other types zeolites, including MOR, MFI ANA.
