Sammanfattning

A new technique of synthesis of mesoporous silica with protonated amino groups avoiding microwave treatment of mesophase was developed using a template method. The block-copolymer P123 was used as a template and sodium meta-silicate with 3-aminopropyltriethoxysilane as precursors. After the removal of template from mesophase with boiling ethanol, the obtained sample displayed highly ordered hexagonal structure with attractive textural parameters: S-BET = 460 m(2) g(-1), V-total = 0.79 cm(3)g(-1) and d = 7.1 nm. FTIR and C-13 CP/MAS NMR spectroscopy revealed the presence of alkyl ammonium groups (0.7 mmol g(-1)) that were able to attach anions of molybdophosphoric acid to the surface of the synthesized mesoporous material. The resulting anion-ion exchange phase can find applications in many areas (adsorption, catalysis, etc.).
