Organik Yapılar (MOFs) sınıfına giren MIL-101, son yıllarda yapılan
çalışmalarda, gelecek vaat eden uygulamalarıyla oldukça dikkat çekmektedir. Nem
ve diğer kimyasallara karşı olağanüstü bir kararlılık sergileyen MIL-101, eşsiz
kristal yapı kombini ile doyamamış krom sitelerinden oluşması gibi üstün
özellikleri ile ayırma süreçleri ve kataliz uygulamalarında kullanımı önem
kazanmıştır. Yapılan çalışmada MIL-101 hidrotermal yöntemle sentezlenmiş ve
karakterizasyonu XRD, azot adsorpsiyon-desorpsiyon analizleri ve SEM ile
yapılmıştır. XRD desenleri MIL-101 karakteristik piklerini taşıdığı göstermiş
ve yüksek yüzey alanlı (~2400 m2/g) malzeme elde edilmiştir. Azot
adsorpsiyon-desorpsiyon analizleri sonucunda malzemenin mezogözenekli malzeme
davranışı gösterdiği görülmüştür.

MIL-101
is a kind of Metal Organic Frameworks (MOFs), which have attracted much
attention in the past decade due to its promising application in chemical
industries. MIL-101 is also known as “Porous Chromium Terephthalate”. It has
very high surface area and pore volume. MIL-101 exhibits exceptional stability
against moisture and other chemicals and is composed of coordinately
unsaturated Cr- sites with high concentration available for catalysis and
adsorption. MIL-101 was synthesized by hydrothermal method and characterized by
XRD, nitrogen adsorption and desorption analyses and SEM. XRD patterns show the
presence of MIL-101’s crystal structure with high surface area (~2400 m2/g).
Nitrogen adsorption-desorption analyzes showed that the material exhibited
mesoporous material behavior.
