Progress of Heterogeneous Iridium-Based Water Oxidation Catalysts.

ACS Nano, 2022
The water oxidation reaction (or oxygen evolution reaction, OER) plays a critical role in green hydrogen production via water splitting, electrochemical CO2 reduction, and nitrogen fixation. The four-electron and four-proton transfer OER process involves

Iridium

2015
Iridium (Ir) belongs to the platinum group elements and is one of the rarest elements in the Earth’s crust. Since Ir is a hard metal with good resistance to corrosion, it is widely used in the electronic, chemical, and automotive industries. In the latter sector, Ir is present as an impurity or is found in alloys together with platinum, palladium, and ...

Trimetallic Iridium–Nickel–Iridium Bis(formazanate) Assemblies

Inorganic Chemistry, 2022
Formazans have attracted a lot of attention in coordination chemistry since the early 1940s because of their unique properties engendered by the nitrogen-rich conjugated backbone. Although many studies have been done using formazanates to chelate transition metals, research using formazanates as building blocks for polynuclear compounds and ...

Atomically dispersed hexavalent iridium oxide from MnO2 reduction for oxygen evolution catalysis

Science
Hexavalent iridium (IrVI) oxide is predicted to be more active and stable than any other iridium oxide for the oxygen evolution reaction in acid; however, its experimental realization remains challenging.
