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 …

Ruthenium is a chemical element that can easily adopt various formal oxidation states from−
II to+ VIII in chemical bonds,(1, 2) thus giving rise to many compounds with interesting and …

Ab initio thermodynamics and first-principles microkinetic simulations have become
standard tools in research on model catalysts. Complementing dedicated in situ experiments …

Operando characterization of working catalysts, requiring per definitionem the simultaneous
measurement of catalytic performance, is crucial to identify the relevant catalyst structure …

The surface chemistry of late transition metal oxides is scientifically interesting and can play
a central role in commercial applications of heterogeneous catalysis. The late transition …

Recent progress in colloidal synthesis of nanoparticles with well-controlled size, shape, and
composition, together with development of in situ surface science characterization tools …

The oxidation of Pt (111) at near-ambient O 2 pressures has been followed in situ using x-
ray photoelectron spectroscopy (XPS) and ex situ using x-ray absorption spectroscopy …

Most metals are oxidized under ambient conditions, and metal oxides show interesting and
technologically promising properties. This has motivated much recent research on oxide …

The concept of coupling a nanometer or subnanometer scale oxide phase to a metal surface
to form a metal–oxide hybrid material with novel properties is an attractive approach in the …

We used scanning tunneling microscopy (STM) to investigate high-coverage structures of
atomic oxygen that develop on Pt (111) under ultrahigh vacuum (UHV) conditions. We find …
