Resumen

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 electropolymerization, electrostatic interaction and chemical bonding. Also, the [Re(bpyac)(CO)₃Cl] rhenium(I) complex for chemical anchorage was analyzed. The characterization of TiO₂/Ru(II) and TiO₂/Re(I) nanocomposite films was performed by field emission scanning electron microscopy (FESEM), electron dispersive X-ray spectroscopy (EDS) and Raman spectroscopy. In addition, for the more stable nanocomposites obtained, the catalytic properties (solar energy conversion and CO₂ reduction) were evaluated. The efficiency improvement in redox process derived from the (photo)electrochemical evidence indicates that modified nanoporous TiO₂ structures enhance the rate of charge transfer reactions.
