dc.description[Ru(NH3)5H2O]3+, [Ru(NH3)5Cl]2+ and [Os(NH3)5H2O]3+ were supported on the hydrated titanium alkoxide grafted on silica gel surface. The mononuclear complexes on the matrix surface have been characterized by specific surface area, elemental analysis, UV-Vis spectroscopy and electrochemical techniques (cyclic voltammetry, differential pulse polarography). These supported species exhibit one defined band on the visible region of the electronic spectrum: band [Ru(NH3)5H2O]3+ (668 nm), [Ru(NH3)5 Cl]2+ (676 nm) and [Os(NH3)5H2O]3+ (825 nm), attributed to MIII → TiIV (M = Ru(III) and Os(III)) metal to metal charge transfer process. For the mononuclear anchored species [Ru(NH3)5H2O]3+, [Ru(NH3)5Cl]2+ and [Os(NH3)5H2O]3+, the (E1/2) for the M(III)/M(II) couple at 25°C are, respectively: -0.22, -0.28, and - 1.15 V versus SCE. A formation of an oxo bridge Ti-O-M(NH3)5 (M = Ru, Os) and chloro bridge Ti-Cl-Ru(NH3)5 was postulated for the grafted complexes on the SiO2/TiO2 surface. © 2000 Elsevier Science B.V.
