Abstract

Metal organic frameworks (MOFs) are a class of organic-inorganic hybrid materials made of metal clusters interconnected through an organic linker. During the last decade, they have attracted wide scientific interests due to their extremely high surface area and pore volume, which can lead to potential applications in gas storage, separation, and heterogeneous catalysis. In this work, a mesoporous chromium terephthalate, MIL-101, having regular pores made of cages of free diameter 3.4 nm and Langmuir surface areas of ca. 5900 m2/g was hydrothermally synthesized and its adsorption and catalytic properties were investigated. High pressure CO2 adsorption properties were measured and found to be higher than those of inorganic mesoporous materials made of silica, carbon, or aluminophosphate. Catalytic performance of MII-101 was evaluated in liquid phase oxidation of tetralin and compared with those of other Cr-containing porous materials, demonstrating high activity and selectivity to 1-tetralone.
