I-Molecular Formula: PtO2
Isisindo se-Molecular: 227.08
I-EINECS: 215-223-0
Okuqukethwe kwe-Pt: Pt≥85.0% (anhydrous), Pt≥80% (hydrate), Pt≥70% (trihydrate)
Omqondofana: I-Platinum(IV) i-oxide, i-platinum dioxide, i-platinic oxide
I-Adams' catalyst, eyaziwa nangokuthi i-platinum dioxide, ivamise ukumelwa njenge-platinum(IV) oxide hydrate, PtO2•H2O. Kuyi-catalyst ye-hydrogenation ne-hydrogenolysis ku-organic synthesis. Le mpushana ensundu emnyama iyatholakala ukudayisa. I-oxide ngokwayo ayiyona into esebenzayo, kodwa iqala ukusebenza ngemva kokuchayeka ku-hydrogen lapho iguqukela ku-platinum emnyama, enesibopho sokusabela.
1. I-Hydrogenation catalyst, ilungele isibopho esiphindwe kabili, isibopho esiphindwe kathathu, i-hydrocarbon enamakha, i-carbonyl, i-nitrile, ukunciphisa i-nitro.
2.Izinto ezinhle kakhulu zokumunca i-hydrogen.
3. Ukumelana nebanga lenani eliphansi lokumelana embonini ye-elekthronikhi.
4. Izinto zokusetshenziswa zezingxenye ezifana ne-potentiometer nezinto zomugqa wefilimu owugqinsi wemboni ye-elekthronikhi.
