Zeolites are well-defined microporous crystalline materials. They are great industrial importance in the gas separation and purificatiion processes and in the petroleum catalytic craking. Huge interest in zeolites is caused by their unique properties that have provided them a vast niche in the industry. Because the pores of the zeolites are similar to many oganic molecules of practical interest, it became possible to design novel catalysts, which control the progress of the reactants and products through them via selecting the molecules by their size and shape.

Metal-organic framework (MOF) is a new class of porous materials. The term "metal-organic framework" implies strong bonding providing robustness, linking unit that are available for modification by organic synthesis, and a geometrically well-defined structure. Metal-organic materials generally consist of metal or metal oxide vertices interconnected by rigid or semi-rigid organic molecules. MOFs may be produced to act as highly selective molecular sieves, sensors or catalysts. However, one of the most promising applications of the MOFs is gas storage. More Info
