Abstract
This paper describes the synthesis and spectroscopic study of a titanium(IV ) silsesquioxane complex, which is heterogenised in the pores of an MCM-41 host material. Its immobilization is performed via chemical bonding, not by means of physical adsorption. As a linking molecule between the MCM-41 car rier and the silsesquioxane, (3-glycidyloxypropyl)trimethoxysilane is used. Characterization is performed by using nitrogen adsorption techniques, TGA , diffuse reflectance infrared spectroscopy (DRIFT) and ICP-MS. Also its ca talytic activity towards the epoxidation of alkenes shows interesting resul ts. (C) 2000 Elsevier Science S.A. All rights reserved.
