I-Adams' catalyst, eyaziwa ngokuba yi-platinum dioxide, idla ngokumelwa njenge-platinum(IV) oxide hydrate, i-PtO2•H2O. Yi-catalyst ye-hydrogenation kunye ne-hydrogenolysis kwi-organic synthesis. Le powder emnyama emdaka iyafumaneka kurhwebo. I-oxide ngokwayo ayisiyo-catalyst esebenzayo, kodwa iyasebenza emva kokuvezwa kwi-hydrogen apho iguquka ibe yi-platinum black, enoxanduva lwe-reactions.
1. I-hydrogenation catalyst, ifanelekile kwi-double bond, i-triple bond, i-aromatic hydrocarbon, i-carbonyl, i-nitrile, kunye ne-nitro reduction.
2.Izixhobo ezibalaseleyo zokufunxa i-hydrogen.
3. Ukumelana okunexabiso eliphantsi lokuxhathisa kushishino lwe-elektroniki.
4. Izinto ezikrwada zezinto ezifana ne-potentiometer kunye nezinto zefilimu ezityebileyo kushishino lwe-elektroniki.
