The development of an effective catalyst is a main point to achieve a successful catalytic process [1]. Among other variables, the pore size must be adequate to facilitate the transport of molecules to or from the active sites. Better transport properties are obtained with mesopores. A very much used method to obtain mesoporous materials is the sol-gel technique, which traditionally is referred to the hydrolisis and condensation of alkoxides, though currently is also used with different precursors [2]. The final porous structure can be adjusted employing an organic compound as pore-forming agent. Different agents, as D-glucose and urea [3,4], were utilized.
