Applications

The most often used oxygen catalyst is ruthenium(IV) oxide. It is applied as an electrochemical super capacitor material, and it has high capacity to store charge. RuO<sub>2</sub> is used as catalyst in the Deacon process which produces chlorine through the oxidation of hydrogen chloride. Owing to the high charge transfer capability, it is used as active material in super capacitors. The dispersion property of RuO2 is used to increase the capacitance of nanocomposite electrode materials for supercapacitors. RuO2 is extensively used for the coating of titanium anodes, and as a catalyst and doping agent, for use in the removal of hydrogen sulfide from oil refineries.

Notes

Incompatible with oxidizers, acids, aqua regia, organic solvents.
