A new technique of synthesis of mesoporous silica with protonated amino groups avoiding microwave treatment of mesophase was developed using template method. The blockcopolymer 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: SBET = 460 m2g-1, Vtotal = 0.79 cm3g-1 and d = 7.1 nm. FTIR and 13C CP/MAS NMR spectroscopy revealed the presence of alkyl ammonium groups (0.7 mmolg-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.).
