MUNGUIA-CORTES, Laura et al. APTES-Functionalization of SBA-15 Using Ethanol or Toluene: Textural Characterization and Sorption Performance of Carbon Dioxide. J. Mex. Chem. Soc [online]. 2017, vol.61, n.4, pp.273-281. ISSN 1870-249X.

SBA-15 materials were functionalized with amino groups, APTES. The functionalization was carried out with ethanol or toluene, in air or nitrogen atmosphere. Texture and silanol ratio of functionalized materials were characterized by CO2 adsorption, N2 adsorption, SEM, TEM, and NMR. The results of this work indicates that functionalization in toluene is better than functionalization in ethanol, in order to anchor the largest number of APTES molecules on SBA-15 surface. For the same purpose, during functionalization process, the use of nitrogen atmosphere is better than the use of air atmosphere.

Palabras clave : APTES; CO2 adsorption; functionalization; SBA-15; silanol ratio.
