Rhodium is a hard, silvery, durable metal that has a high reflectance. Rhodium metal does not normally form an oxide, even when heated. [25] Oxygen is absorbed from the atmosphere only at the melting point of rhodium, but is released on solidification. [26] Rhodium has both a higher melting point and lower density than platinum.
Rhodium oxide films are transparent and conductive, like indium tin oxide (ITO) - the common transparent electrode, but Rh 2 O 3 has 0.2 eV lower work function than ITO. Consequently, deposition of rhodium oxide on ITO improves the carrier injection from ITO thereby improving the electrical properties of organic light-emitting diodes. [5]

Rhodium(IV) oxide (or rhodium dioxide) is the chemical compound with the formula Rh O 2. Chemical properties. RhO 2 is highly insoluble even in hot aqua regia. [1]
Organorhodium chemistry is the chemistry of organometallic compounds containing a rhodium-carbon chemical bond, and the study of rhodium and rhodium compounds as catalysts in organic reactions. [ 1 ] Stable organorhodium compounds and transient organorhodium intermediates are used as catalyst such as in olefin hydroformylation , olefin ...
Noble metals tend to be resistant to oxidation and other forms of corrosion, and this corrosion resistance is often considered to be a defining characteristic. Some exceptions are described below. Copper is dissolved by nitric acid and aqueous potassium cyanide .
Rhodium oxide can refer to: Rhodium(III) oxide, Rh 2 O 3; Rhodium(IV) oxide, RhO 2 This page was last edited on 31 December ...
