Comparative study of the anchorage and the catalytic properties of nanoporous TiO2 films modified with ruthenium (II) and rhenium (I) carbonyl complexes.
In this article we study the anchoring of cis-[Ru(bpyC4pyr)(CO)2(CH3CN)2]2+, cis-[Ru(bpy)2(CO)2]2+ and cis-[Ru(bpyac)(CO)2Cl2], onto nanoporous TiO2 employing electropolymn., electrostatic interaction and chem. bonding. Also, the [Re(bpyac)(CO)3Cl] rhenium(I) complex for chem. anchorage was analyzed. The characterization of TiO2/Ru(II) and TiO2/Re(I) nanocomposite films was performed by field emission SEM (FESEM), electron dispersive X-ray spectroscopy (EDS) and Raman spectroscopy. In addn., for the more stable nanocomposites obtained, the catalytic properties (solar energy conversion and CO2 redn.) were evaluated. The efficiency improvement in redox process derived from the (photo)electrochem. evidence indicates that modified nanoporous TiO2 structures enhance the rate of charge transfer reactions.
