Paraguay-Delgado Física, Astronomía y Matemáticas Acidity Dehydration Mesoporous silicate Mesoporous silicate were synthesized by a not hydrothermal method and the acid sites were promote by adding zirconium and sulfate ions. The maximum acid strength of the mesoporous silicate was promoted by addition of zirconium during the synthesis process and sulfate ions was add by insipient impregnation, after the mesoporous silicate synthesis. The materials were characterized by TGA, XRD, FT-IR, BET, potentiometric titration with n-butylamine, SEM and TEM techniques. The catalytic activity of the materials was evaluated for the ethanol dehydratation. The zirconium atoms and sulfate ions incorporation had a favorable impact on the acid strength of sites going from -42 to 143 mV. The hexagonal arrangement mesoporous material is slightly affected, indicating that ZrO2 nano crystals are within the silicate matrix. At the same way affected the sulfate ions presence. 2015 artículo científico 1665-3521 https://www.redalyc.org/articulo.oa?id=94243132004 es http://www.redalyc.org/revista.oa?id=942 Superficies y vacío application/pdf Sociedad Mexicana de Ciencia y Tecnología de Superficies y Materiales A.C.
