용도RH2o3 is used to make rhodium metal and its various salts. Also, the oxide is a catalyst for hydrogenation.
생산 방법Rhodium(III) oxide, Rh2O3, can be prepared by heating the finely divided metal or its nitrate in air or O2. The rhodium(IV) oxide is also known. Rhodium trihydroxide may be precipitated as a yellow compound by adding the stoichiometric amount of KOH to a solution of RhCl3. The hydroxide is soluble in acids and excess base. When the freshly precipitated Rh(OH)3 is dissolved in HCl at a controlled pH, a yellow solution is first obtained in which the aquochloro complex of Rh behaves as a cation.
