%X Titania modified mesoporous slilcate MCM-41 (MCM-TiO2) was synthesized by precursor tetrabutyltitanate and calcined MCM-41. Au clusters deposited on the inner surface of titania-modified MCM-41 by the photodeposition method through AuCl-4 and MCM-TiO2 reaction. The structure and optical properties of the as-synthesized samples were investigated by XRD, XPS, N2 adsorption/ desorption isotherms and diffuse reflectance UV-Vis absorbance spectroscopy. The decrease of BET surface areas and the pore volume proved that nanosized Au clusters deposited in the mesopore of MCM-TiO2. The Au 4f of XPS and the plasmon absorption in UV-Vis spectrum showed that the deposited Au was in metal state.
