Adams 'catalyst, tseem hu ua platinum dioxide, feem ntau yog sawv cev ua platinum (IV) oxide hydrate, PtO2•H2O.Nws yog ib qho catalyst rau hydrogenation thiab hydrogenolysis hauv organic synthesis.Cov hmoov av dub no yog muag muag.Lub oxide nws tus kheej tsis yog ib qho active catalyst, tab sis nws ua active tom qab raug hydrogen whereupon nws hloov mus rau platinum dub, uas yog lub luag hauj lwm rau cov kev tshwm sim.
1. Hydrogenation catalyst, haum rau ob daim ntawv cog lus, triple daim ntawv cog lus, aromatic hydrocarbon, carbonyl, nitrile, nitro txo.
2.Cov khoom siv hydrogen zoo heev.
3. Kev ua haujlwm tsis zoo nrog cov nqi qis qis hauv kev lag luam hluav taws xob.
4. Cov khoom siv raw rau cov khoom siv xws li potentiometer thiab tuab zaj duab xis kab cov ntaub ntawv rau kev lag luam hluav taws xob.
