[Product Description]
Ruthenium(IV) oxide (RuO2) is a black chemical compound containing the rare metal ruthenium and oxygen.
The most often used O2 catalyst is ruthenium(IV) oxide, however care must be taken since hydrates of this oxide exist.
RuO2 is generally used as a catalyst in various industrial applications or an electrode in electrochemical processes. RuO2 is highly reactive with reducing agents, due to its oxidizing properties.

[Application]
RuO2 is extensively used for the coating of titanium anodes for the electrolytic production of chlorine and for the preparation of resistors or integrated circuits.
Ruthenium(IV) oxide is a versatile catalyst and doping agent. hydrogen sulfide can be split by light by using a photocatalyst of CdS particles doped with ruthenium(IV) oxide loaded with ruthenium dioxide.This may be useful in the removal of H2S from oil refineries and from other industrial processes. The hydrogen produced could be used to synthesize ammonia, methanol, and possibly fuel a future hydrogen economy.
Ruthenium (IV) oxide is being used as the main component in the catalyst of the Deacon process which produces chlorine by the oxidation of hydrogen chloride.
