High-density modification of mesoporous silica inner walls with amino acid function by residue transfer from template

摘要

Novel surfactants containing an alkoxysilane group and an amino acid residue have been synthesized. Using these surfactants as templates, mesoporous silica/surfactant covalent composites were prepared. Selective removal of the alkyl chain of the template provided mesoporous silica with inner surface densely covered by the amino acid residue. Successful modification process was confirmed by XRD, FT-IR, TEM and TGA analyses.
