<p>This work presents the preparation of mesoporous aluminum silicates from condensation of xerogel obtained from Tetraethyl orthosilicate (TEOS) and other aluminum precursos from various sources. The reagents used were aluminum nitrate (NAN) as inorganic source and the inorganic-alkoxide, Aluminun tris-secbutilate (TBA) as organometallic source. The length of the alkyl chain was evaluated in regards to its influence upon the surface area and in the generation of mesopores in the materials. Additionally, the former parameters were studied to determine their effect on the hydrothermal stability of the aluminosilicates.</p>
