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 …

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 …

Despite its importance in oxidation catalysis, the active phase of Pt remains uncertain, even
for the Pt (111) single-crystal surface. Here, using a ReactorSTM, the catalytically relevant …

Studies show that the rate of CO oxidation on Pt-group metals at temperatures between 450
and 600K and pressures between 1 and 300Torr increases markedly with an increase in the …

Flow reactor experiments and XPS measurements were used to investigate the observed
decrease in activity of Pt/Al2O3 and Pt/BaO/Al2O3 catalysts during reaction conditions. The …

Platinum (Pt) oxides are vital catalysts in numerous reactions, but research indicates that
they decompose at high temperatures, limiting their use in high-temperature applications. In …

The surface oxidation of a polycrystalline silver foil by reaction with ozone (5mol% O3 in O2)
at 300K and ambient pressure was investigated. The morphology, microstructure and …

This article presents a systematic study of the formation and thermal stability of Pt oxide
species on size-selected Pt nanoparticles (NPs) supported on SiO2, ZrO2, and TiO2 thin …

The method of X-ray photoelectron spectroscopy was used to study the interaction of the
model Pt/TiO2 catalysts with NO2 and the following reduction of the oxidized Pt …

The coverage of surface adsorbates influences both the number and types of sites available
for catalytic reactions at a heterogeneous surface, but accounting for adsorbate–adsorbate …
