Resumen:
The adsorption of aniline on Na-AlMCM-41 material synthesized by us, has been characterized by thermo-infrared spectroscopy, temperature programmed desorption (TPD) and differential thermal analysis methods. Aniline would be mostly bound to mesostructure through weak ð interactions. On the mesostructure containing adsorbed water, the co-adsorption of aniline could occur by weak hydrogen bonding through surface water molecules. For water, two possible modes of adsorption have been identified. Different associations between aniline and hydrated and non-hydrated mesostructure have been evaluated in order to favor the posterior in-situ polymerization of adsorbed aniline.
