Abstract

Abstract: γ-thiopropyl tri-methyl silicane and surface pre-adsorption hydrolysis technique were used to accommodate CdS and TiO2 nanoparticles into the tunnels of MCM-41 meso-porous sieves. UV-Vis spectra showed that MCM-41 extracted CdS 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.

Key words: CdS, 　TiO2, 　MCM-41, 　Nano-composite
