Yeni Nesil MIL-101 Malzemesi Sentez ve Karakterizasyon Çalışmaları

Öz

Metal 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.

Synthesis and Characterization Studies of MIL-101

Abstract

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.
