摘要：

gamma-thiopropyl tri-methyl silicane and surface pre-adsorption hydrolysis technique were used to accommodate US and TiO2 nanoparticles into the tunnels of MCM-41 meso-porous sieves. UV-Vis spectra showed that MCM-41 extracted US nanoparticles effectively from the reverse micelles by the chelation of thiol- groups. The changes of meso-tunnel diameter of MCM-41 were also observed with the introducing of nanoparticles in the low angle XRD patterns.
