| Abstract: | Highly ordered amino-functionalized mesoporous silica thin films(MTFs) were directly synthesized by co-condensation of tetraethoxysilane(TEOS) and 3-aminopropyltriethoxysilane(APTES) in the presence of P123(EO20PO70EO20).According to the neutralization-reaction mechanism followed by a reduction procedure of hydrogen-ambience calcinations,gold nanoparticles were introduced into the pore channels of amino-functionalized MTFs,and the Au/SiO2 nanocomposite was obtained.The nanomaterials were characterized by XR... |
