Microporous materials with regular pore architecture comprise wonderfully complex structures and compositions. Their fascinating properties, such as catalysts and their roles as hosts in nanocomposite materials, are essentially determined by their unique structural characters [1]. Zeolites constitute the most important family in microporous materials; a representative example of a widely used zeolite is LTA. Zeolites possess acid sites on the surface which can catalyse many reactions, this acidity might be increased by introducing transition metals in different oxidation and coordination states, and so, the incorporation of Niobium into microporous molecular sieves brings up new properties for these materials as a solid acid catalyst.[1].
