Nanostructured Iridium Oxide: State of the Art

Iridium Oxide (IrO2) is a metal oxide with rutile crystalline structure, analogous to the TiO2 polymorph. Unlike other oxides of transition metals, IrO2 shows metallic type conductivity and displays low surface work function. also characterized by high chemical stability. These highly desirable properties make rightful candidate for specific applications. Furthermore, can be synthesized in form wide variety nanostructures ranging from nanopowder, nanosheets, nanotubes, nanorods, nanowires, nanoporous thin films. nanostructuration, which allows its attractive intrinsic enhanced, therefore exploited according pursued application. Indeed, have shown utility fields that span electrocatalysis, electrochromic devices, sensors, fuel cell supercapacitors. After brief description structure properties, present review will describe main employed synthetic methodologies are followed prepare selectively various types nanostructures, highlighting each case advantages brought nanostructuration illustrating their performances
