The activation of O2 on metal surfaces is a critical process for heterogeneous catalysis and
materials oxidation. Fundamental studies of well-defined metal surfaces using a variety of …

Using photoemission spectroscopy techniques, we show that oxygen intercalation is
achieved on an extended layer of epitaxial graphene on Ir (111), which results in the “lifting” …

The chemisorption of atomic (H, O, N, S, C), molecular (N2, CO, NO, NH3), and radical (CH3,
OH, NOH) species on Ir (111) has been systematically studied. Self-consistent, periodic …

RuO 2+ IrO 2 electrodes of various compositions from 0 to 100% RuO 2 have been prepared
by thermal decomposition of RuCl 3+ IrCl 3 in isopropanol solutions. The surface and …

Adsorption of N2, O2, N2O and NO on a clean Ir (111) surface at 84 K has been studied by
high resolution EELS and TPD. N2, O2 and N2O desorb reversibly with the desorption peak …

The surface composition of RuO 2+ IrO 2 mixed oxide layers (1–2 μm thick) deposited on
titanium by thermal degradation of the corresponding chlorides in aqueous or isopropanol …

The coverage dependence of oxygen adsorption energies on the fcc (111) surfaces of seven
different transition metals (Rh, Ir, Pd, Pt, Cu, Au, and Ag) is demonstrated through density …

The adsorption and dissociation of O2 on Ir (100) has been studied with X-ray photoelectron
spectroscopy (XPS), low energy electron diffraction (LEED) and scanning tunneling …

The oxidation of the Ir (111) surface was studied by in situ surface X-ray diffraction (SXRD) in
an oxygen pressure range of 10− 6− 100 mbar at temperatures from 575 to 875 K, in …

Iridium-based materials are among the most active bifunctional catalysts in heterogeneous
catalysis and electrocatalysis. We have investigated the properties of atomically defined …
