Preparation and Structure Characterization of Pt Clusters on Titania Modified MCM-41
Source abstract
Abstract
Pt clusters deposited on titania－modified MCM-41 were synthesized by a photodepo- sition method through PtCl and titania－modified MCM-4l. The structure and optical properties of the samples were investigated by XRD, XPS, N2 adsorption/desorption isotherms and diffuse reflectance UV-Vis absorption spectroscopy. The results of XPS showed that the deposited Pt was in metal state. Although the BET surface areas and pore volume decreased because of the introduction of Pt, the pore diameter distribution was almost not affected. The curve of Pt de- posited titania modified MCM-41 in UV-Vis absorption spectrum was different from that of titania modified MCM-41.
