Abstract

A new organosilane template with double-carbamate carbon chains were synthesized for preparation of mesoporous zeolites. The structure of the acquired zeolite crystals was confirmed by scanning electron microscopy (SEM), transmission electron microscopy (TEM), nitrogen adsorption-desorption measurements, and X-ray diffraction (XRD), which indicated that their structure has the same characteristics as ZSM-5 zeolites, and there were about 4 nm and 6 nm mesopores in the acquired zeolites.

Kurzfassung

Für die Hserstellung von mesoporösen Zeolithen wurde ein neues Organosilan-Templat mit Doppelcarbamat-Kohlenstoffketten synthetisiert. Die Struktur der erworbenen Zeolithkristalle wurde durch Rasterelektronenmikroskopie (SEM), Transmissionselektronenmikroskopie (TEM), Stickstoffadsorptions-Desorptionsmessungen und Röntgenbeugung (XRD) bestätigt, was darauf hinweist, dass ihre Struktur die gleichen Eigenschaften aufweist wie ZSM-5 Zeolithe, und in den erhaltenen Zeolithen befanden sich etwa 4 nm und 6 nm große Mesoporen.
