• Uses: ▼▲ Industry Application Role/benefit Hydrogenation Reduction of alkynes to alkenes Catalyst/ In the presence of H2，PtO2 can be reduced to Pt black which is the active form Hydrogenation of nitro compounds to amines Hydrogenation of ketones The removal of phenyl groups attached to a heteroatom Reduction of aromatic ring Dehydrogenation Dehydrogenation of 1,4-diketone to pyridazine Oxidation Oxidation of alcohols to carbonyl compounds Others Resistance Low resistance range Hydrogen absorbing material Excellent hydrogen absorbing capacity Thick film circuit and electronic component Insoluble in aqueous solutions (water) and extremely stable Solid oxide fuel cells and oxygen generation systems Cathode/certain perovskite structured oxides are electronically conductive As catalyst in hydrogenations. The actual catalyst is platinum black which is formed in situ by reduction of the PtO2 by the hydrogen used for the hydrogenation. Especially useful for reduction at room tempereture and hydrogen pressures up to 4 atmospheres. Suitable for the reduction of double and triple bonds, aromatic nuclei, carbonyl groups, nitro groups, and nitriles. Platinum(IV) oxide is used as catalyst for hydrogenation reactions. It is applied in the hydrogenation of alkenes to alkanes, nitro compounds to amines and ketones to alcohols. It is also involved in the hydrogenolysis of cyclopropyl group in to an isopropyl group and in selective oxidation of primary alcohols. Platinum(IV) oxide has been used for the reduction of citernyl bromide to form (S)-3,7-dimethyloctylbromide.
• Description: PTO2 is an alternating wide band-gap copolymer?with electron-donating benzodithiophene (BDT) and? electron-withdrawing?thiophene carboxylate ester as the main backbone units. PTO2 enjoys good solubility in non-halogenated solvents, i.e. xylenes and THF.
