Uses & manufacturing

General Manufacturing InformationRuthenium oxide (RuO2): ACTIVE

Applications · 2 items

DescriptionRuthenium dioxide/ Ruthenium (IV) oxide is a black/purple solid at room temperature that is used as an electro-catalyst in chlorine oxide, chlorine and oxygen-producing reactions. Ruthenium dioxide is made of a rutile crystal structure that resembles that of titanium oxide and other closely-linked metal oxides. Its structure enhances the formation of hydrates, and it also has a great potential to store charge when applied to aqueous solutions.

UsesRuthenium(IV) Oxide Anhydrous is a research reagent and applied for exfoliation of layered metal oxide nanosheets.

Preparation methods · 1 item

PreparationRuthenium dioxide is prepared through various methods. The preparation methods highlighted below indicate the preparation of Ruthenium dioxide as a film. Through electroplating where the film is passed through a solution of RuCl3.xH2O, where a Pt gauze is applied as the electrode in the opposite direction whereas Ag/AgCl is the source electrode. Through chemical vapor deposition (CVD) of Ruthenium dioxide from appropriate volatile ruthenium agents. Through heating or pyrolysis of Ruthenium halides, preferably covering the substrate by spraying a solution of the halide on the heated substrate. The suitable halide for this method of preparation is Ruthenium (III) chloride to form Ruthenium (IV) OXIDE. This method of preparation has been developed further by scholars such as Schafer for the synthesis of partly stoichiometric Ruthenium dioxide single crystals. Nonetheless, each of the preparation procedures takes on a similar reaction mechanism: Ru+(IV) + O2 (heat)→ RuO2 The application of bouts of high temperatures of heat (about 15000 C) can eliminate all contaminants and oxides from the reaction, and allow for the formation of a new oxide coating on the surface of Ruthenium.
