Adams 'catalyst, tseem hu ua Platinum Dioxide, feem ntau yog sawv cev li platinum (iv) oxide hydrate, pto2 • h2o. Nws yog catalyst rau hydrogenation thiab hydrogenolysis hauv synthesis. Qhov no tsaus xim av hmoov yog cov lag luam muaj. Oxide nws tus kheej tsis yog ib qho kev nquag ua haujlwm tom qab raug rau hydrogen whereupon no nws converts rau platinum dub, uas yog lub luag haujlwm rau cov kev cuam tshuam.
1. Hydrogenation catalyst, haum rau ob peb daim ntawv cog lus, khi khi, muaj ntxhiab hydrocarbon, carbonyl, nitro txo.
2.Zoo heev hydrogen deav cov ntaub ntawv.
3. Kev tawm tsam nrog cov nqi tiv thaiv tsawg hauv cov kev lag luam hluav taws xob.
4. Cov khoom siv raw rau cov khoom xws li cov khoom siv xws li cov kab ua yeeb yaj kiab cov kab rau hluav taws xob kev lag luam.
