WebbLTL zeolites with sizes ranging from nanometers to micrometers and disc-shaped or barrel-like morphologies have already been reported [ W_ , 20 ]. Herein, we present a novel synthetic approach relied on the use of microwave-assisted heating for the production of high quality LTL zeolite crystals with tunable size and morphology.

In Situ SAXS/WAXS of Zeolite Microwave Synthesis: NaY, NaA, …
WebbMesoporous MFI zeolites (ZSM-5, TS-1, S-1) having intracrystalline mesoporosity within zeolite crystals were synthesized by microwave induced assembly through the ionic interaction between the sulfonic acid functionalized MFI zeolite nanoparticles and alkyltrimethylammonium cationic surfactants. Webb(Sn or Ti) species is added during MFI zeolite synthesis, nearly no difference between two synthesis systems can be observed even if the crystallization temperature is decreased to 130 C (Fig. 3). Therefore, we deduce that this microwave effect is derived from the interaction between microwave eld and heteroatom species. eastcote care home haverhill
