| description | Iridium Oxide (IrO<sub>2</sub>) is a metal oxide with a rutile crystalline structure, analogous to the TiO<sub>2</sub> rutile polymorph. Unlike other oxides of transition metals, IrO<sub>2</sub> shows a metallic type conductivity and displays a low surface work function. IrO<sub>2</sub> is also characterized by a high chemical stability. These highly desirable properties make IrO<sub>2</sub> a rightful candidate for specific applications. Furthermore, IrO<sub>2</sub> can be synthesized in the form of a wide variety of nanostructures ranging from nanopowder, nanosheets, nanotubes, nanorods, nanowires, and nanoporous thin films. IrO<sub>2</sub> nanostructuration, which allows its attractive intrinsic properties to be enhanced, can therefore be exploited according to the pursued application. Indeed, IrO<sub>2</sub> nanostructures have shown utility in fields that span from electrocatalysis, electrochromic devices, sensors, fuel cell and supercapacitors. After a brief description of the IrO<sub>2</sub> structure and properties, the present review will describe the main employed synthetic methodologies that are followed to prepare selectively the various types of nanostructures, highlighting in each case the advantages brought by the nanostructuration illustrating their performances and applications. |
