ʻO Adams' catalyst, i ʻike ʻia he platinum dioxide, ka mea maʻamau i hōʻike ʻia he platinum(IV) oxide hydrate, PtO2•H2O.He mea hoʻoikaika ia no ka hydrogenation a me ka hydrogenolysis i ka synthesis organik.Hiki ke kūʻai ʻia kēia pauda ʻeleʻele ʻeleʻele.ʻO ka oxide ponoʻī ʻaʻole ia he catalyst ikaika, akā lilo ia i mea ikaika ma hope o ka ʻike ʻana i ka hydrogen kahi e hoʻololi ai i ka platinum ʻeleʻele, nona ke kuleana no nā hopena.
1. Hydrogenation catalyst, kūpono no ka paʻa pālua, paʻa ʻekolu, hydrocarbon aromatic, carbonyl, nitrile, nitro reduction.
2.ʻO nā mea hoʻoheheʻe hydrogen maikaʻi loa.
3. Kū'ē me ka haʻahaʻa haʻahaʻa kumu waiwai i loko o ka ʻoihana uila.
4. Nā lako maka no nā ʻāpana e like me ka potentiometer a me nā mea laina kiʻiʻoniʻoni mānoanoa no ka ʻoihana uila.
