Adams' catalyst, nke a makwaara dị ka platinum dioxide, na-anọchi anya ya dị ka platinum(IV) oxide hydrate, PtO2•H2O.Ọ bụ ihe na-eme ka hydrogenation na hydrogenolysis na njikọ organic.Uzuzu aja aja gbara ọchịchịrị a na-ere ahịa.Oxide n'onwe ya abụghị ihe na-arụ ọrụ, mana ọ na-arụ ọrụ mgbe ekpughere ya na hydrogen ebe ọ na-atụgharị na platinum ojii, nke na-ahụ maka mmeghachi omume.
1. Ihe na-akpata hydrogenation, dabara adaba maka njikọ abụọ, njikọ atọ, hydrocarbon aromatic, carbonyl, nitrile, mbelata nitro.
2.Ihe nnabata hydrogen kacha mma.
3. Nguzogide nwere oke nguzogide dị ala na ụlọ ọrụ eletrọnịkị.
4. Akụrụngwa maka akụrụngwa dịka potentiometer na ngwa ahịrị ihe nkiri siri ike maka ụlọ ọrụ eletrọnịkị.
