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 …

Highly crystalline single-domain magnetite Fe3O4 nanoparticles (NPs) are important, not
only for fundamental understanding of magnetic behaviour, but also for their considerable …

Iron oxides play an increasingly prominent role in heterogeneous catalysis, hydrogen
production, spintronics, and drug delivery. The surface or material interface can be …

Iron oxide nanoparticles are of great scientific interest due to their huge versatility of
applications. The oxidation process of magnetite to maghemite is difficult to monitor as both …

Nanostructured hematite (α-Fe2O3) shows promise as a semiconductor for
photoelectrochemical (PEC) water oxidation. However, it suffers from inadequate charge …

The renewed interest in magnetite (Fe3O4) as a major phase in different types of catalysts
has led us to study the oxidation–reduction behaviour of its most prominent surfaces. We …

Most of the treatment strategies for tumors and other disorders is photodynamic therapy
(PDT). For several years, increasing the efficiency of nanostructured treatment devices …

We present a comprehensive investigation, via first-principles density functional theory
(DFT) calculations, of various surface terminations of magnetite, Fe3O4 (111), a major iron …

Metal–support interactions are frequently invoked to explain the enhanced catalytic activity
of metal nanoparticles dispersed over reducible metal oxide supports, yet the atomic‐scale …

Heterogeneous catalysts based on subnanometer metal clusters often exhibit strongly size-
dependent properties, and the addition or removal of a single atom can make all the …
