Chemische Eigenschaften
grey to black powder
Physikalische Eigenschaften
Greenish black tetragonal crystals; density 8.3 g/cm³; decomposes to Pd metal at 750°C; insoluble in water and acids; slightly soluble in aqua regia.
Verwenden
Reduction catalyst in synthesis of organic Compounds.
Verwenden
Palladium(II) oxide is used to prepare palladium catalyst for hydrogenation. The oxide is readily reduced by hydrogen to metal.
Verwenden
Catalytic reduction, in organic synthesis.Palladium(II) oxide is used as a catalyst for reduction in organic synthesis. It is an excellent gas sensing material for carbon monoxide at low working temperatures. It is also used in the preparation of good optical quality films. It is involved in the preparation of LuPd2O4 , which is used in superconducting materials.
synthetische
Palladium(II) oxide is prepared by heating palladium sponge in oxygen at 350°C. The oxide is obtained as a black powder. The oxide also may be prepared specially for catalytic use by heating a mixture of palladium chloride and potassium nitrate at 600°C and then leaching out water-soluble residue. A hydrated form of the oxide, which is acid soluble can be prepared by precipitation from solution, for example, by hydrolysis of palladium nitrate. The brown hydrated oxide converts to black anhydrous oxide on heating. Its solubility in acids decreases with lowering of water content.
