To enhance the application of siliceous mesoporous molecular sieves for catalytic applications, various metal ions have been incorporated and applied for various types of reactions. One such transition metal is zirconium which imparts Lewis acidic character to mesoporous silicates [1, 2]. KIT-6 is a large pore cubic Ia3d mesoporous silicate [3]. Its tunable pore size (4 - 12 nm) and pore wall thickness might overcome disadvantages of various well-known mesoporous silicates. In the present study, we have attempted the direct incorporation of zirconium in to the mesoporous framework of KIT-6 using triblock copolymers as the structure-directing agent in the presence of n-butanol. Physicochemical Properties such as XRD, nitrogen sorption, FTIR, UV-Vis and ammonia-TPD of Zr-KIT-6 are presented. The acidity of this material is correlated with the activity for cyclohexanol dehydration.
