Metal atoms dispersed on the oxide supports constitute a large category of single-atom
catalysts. In this review, oxide supported single-atom catalysts are discussed about their …

The field of single-atom catalysis (SAC) has expanded greatly in recent years. While there
has been much success developing new synthesis methods, a fundamental disconnect …

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 …

Doping magnetite surfaces with transition-metal atoms is a promising strategy to improve the
catalytic performance toward the oxygen evolution reaction (OER), which governs the …

Enhancing the deep reduction of Fe 2 O 3 oxygen carriers (OCs) is a major challenge in the
chemical looping hydrogen production (CLH) process. To solve this issue, the modification …

Single-atom catalysis has been a topic of increasing interest due to the potential for
improved selectivity, reactivity, and catalyst cost. However, single-atom catalysts are still …

The Fe3O4 nanozyme, the first reported nanozyme with intrinsic peroxidase-like activity, has
been successfully employed for various diagnostic applications. However, only a few studies …

Electrochemical water splitting is an environmentally friendly technology to store renewable
energy in the form of chemical fuels. Among the earth-abundant first-row transition metal …

Fenton's reagent provides a method to produce active hydroxyl radicals (˙ OH) for chemical
oxidation by mixing iron oxide and hydrogen peroxide, which divides into homogeneous …

The structure of a catalyst often changes in reactive environments, and following the
structural evolution is crucial for the identification of the catalyst's active phase and reaction …
