Ifomula Yamamolekyuli: PtO2
Isisindo sama-molecule: 227.08
I-EINECS: 215-223-0
Okuqukethwe kwe-Pt: Pt≥85.0% (engenamanzi), Pt≥80% (i-hydrate), Pt≥70% (i-trihydrate)
Amagama afanayo: i-platinum(IV) oxide, i-platinum dioxide, i-platinic oxide
I-catalyst ka-Adams, eyaziwa nangokuthi i-platinum dioxide, ivame ukumelwa njenge-platinum(IV) oxide hydrate, i-PtO2•H2O. Iyi-catalyst ye-hydrogenation kanye ne-hydrogenolysis ekuhlanganisweni kwezinto eziphilayo. Le mpuphu ensundu emnyama iyatholakala kwezentengiselwano. I-oxide ngokwayo ayiyona i-catalyst esebenzayo, kodwa iba yingozi ngemva kokuchayeka ku-hydrogen lapho iguqukela ku-platinum black, okuyiyona ebangela ukusabela.
1. I-Hydrogenation catalyst, efanelekile ukubopha okuphindwe kabili, ukubopha okuphindwe kathathu, i-aromatic hydrocarbon, i-carbonyl, i-nitrile, ukunciphisa i-nitro.
2.Izinto ezinhle kakhulu zokumunca i-hydrogen.
3. Ukumelana okunezinga eliphansi lokumelana embonini kagesi.
4. Izinto zokusetshenziswa zezingxenye ezifana ne-potentiometer kanye nezinto zomugqa wefilimu obukhulu embonini ye-elekthronikhi.
