The current status of knowledge regarding the surfaces of the iron oxides, magnetite (Fe 3 O
4), maghemite (γ-Fe 2 O 3), haematite (α-Fe 2 O 3), and wüstite (Fe 1− x O) is reviewed. The …

Polar surfaces of compound materials have been the subject of intense activity in the past.
Electrostatic arguments, based on a model of rigid charges, predict that they should have an …

The diffusion of hydrogen atoms across solid oxide surfaces is often assumed to be
accelerated by the presence of water molecules. Here we present a high-resolution, high …

Carbon-supported, Pt and PtCo nanocrystals (NCs) with controlled size and composition
were synthesized and examined for hydrodeoxygenation (HDO) of 5-hydroxymethylfurfural …

The interaction of atomic hydrogen and H2O with stoichiometric and partially reduced CeO2
(111) thin films deposited on a Cu (111) substrate was investigated by temperature …

Transition metal oxides show great promise as Earth-abundant catalysts for the oxygen
evolution reaction in electrochemical water splitting. However, progress in the development …

Thin oxide films grown on metal single-crystal substrates have been successfully used as
suitable supports to model disperse metal catalysts.[1–9] This is even true of ultrathin films (2 …

We present an integrated procedure for the synthesis of infinite-layer nickelates using
molecular-beam epitaxy with gas-phase reduction by atomic hydrogen. We first discuss …

The reduction of a Cu2O surface layer on Cu (111) by CO was studied using scanning
tunneling microscopy (STM), X-ray photoelectron spectroscopy (XPS) and calculations …

Within the area of surface science, one of the “holy grails” is to directly visualize a chemical
reaction at the atomic scale. Whereas this goal has been reached by high-resolution …
