Ruthenium(IV) oxide is the inorganic compound with the formula Ru O 2. This black solid is the most common oxide of ruthenium . It is widely used as an electrocatalyst for producing chlorine, chlorine oxides, and O 2 . [ 1 ]
Electronics is the largest use of ruthenium. [23] Ru metal is particularly nonvolatile, which is advantageous in microelectronic devices. Ru and its main oxide RuO 2 have comparable electrical resistivities. [70] Copper can be directly electroplated onto ruthenium, [71] particular applications include barrier layers, transistor gates, and ...
Ruthenium can be oxidized to ruthenium(IV) oxide (RuO 2, oxidation state +4), which can, in turn, be oxidized by sodium metaperiodate to the volatile yellow tetrahedral ruthenium tetroxide, RuO 4, an aggressive, strong oxidizing agent with structure and properties analogous to osmium tetroxide.
Ruthenium oxide may refer to either of the following: Ruthenium(IV) oxide, RuO 2; Ruthenium(VIII) oxide, RuO 4 This page was last edited on 13 May 2022 ...
While the perruthenate anion serves as the oxidising agent in this reaction, rather than a true catalyst, it is quickly restored by an appropriate cooxidant such as N-methylmorpholine N-oxide. [ 1 ] Tetrapropylammonium perruthenate (TPAP) is the most widely used of these reagents, though some alternatives have been proposed which offer greater ...
Ruthenium tetroxide is the inorganic compound with the formula RuO 4. It is a yellow volatile solid that melts near room temperature. [3] It has the odor of ozone. [4] Samples are typically black due to impurities. The analogous OsO 4 is more widely used and better known.

Henri Bernard Beer registered his patent on mixed metal oxide electrodes in 1965. [2] The patent named "Beer 65", also known as "Beer I", which Beer claimed the deposition of Ruthenium oxide, and admixing a soluble titanium compound to the paint, to approximately 50% (with molar percentage RuO 2:TiO 2 50:50).
