Isku macno ah: Platinum(IV) oxide, platinum dioxide, platinum oxide
Kataliyayaasha Adams, oo sidoo kale loo yaqaan platinum dioxide, badanaa waxaa loo matalaa platinum(IV) oxide hydrate, PtO2•H2O. Waa kataliyayaasha hydrogenation iyo hydrogenolysis ee isku-darka dabiiciga ah. Budadan bunni madow ayaa ganacsi ahaan laga heli karaa. Oksaydhka laftiisu maaha kataliyeyaasha firfircoon, laakiin wuxuu noqdaa mid firfircoon ka dib marka la soo bandhigo haydarojiin halkaas oo uu isu beddelo madow platinum ah, kaas oo mas'uul ka ah falcelinta.
1. Kataliyayaasha haydarojiinta, oo ku habboon isku xidhka labanlaabka ah, isku xidhka saddexlaha ah, haydarojiinta udgoonka leh, carbonyl, nitrile, iyo dhimista nitro.
2.Agab aad u fiican oo nuugista haydarojiin ah.
3. Iska caabinta oo leh qiime iska caabin hooseeya warshadaha elektaroonigga ah.
4. Alaab ceeriin ah oo loogu talagalay qaybaha sida potentiometer iyo agabka xariiqda filimka ee qaro weyn ee warshadaha elektaroonigga ah.
