Abstract

Molecular level electronic information obtained using ultraviolet photoelectron spectroscopy (UPS) is presented for titanium-dioxide-bound organometallic complexes produced in the ultrahigh vacuum (UHV) environment. These covalently bound organometallic complexes are produced by reacting the hydroxylated TiO₂(001) low temperature facetted surface with vapor of tris(allyl)rhodium. UPS, AES, and ELS data for this species, as well as for the di(allyl)rhodium oxide-bound species and the product of its hydrogenation are presented. The UPS data indicate that 2p electrons originating from the oxygen of the support have a lower BE peak maximum for the rhodium hydrides than for the di(allyl)rhodium bound species.
