Cov ntsiab lus Pt: Pt≥85.0% (anhydrous), Pt≥80% (hydrate), Pt≥70% (trihydrate)
Cov Lus Txhais: Platinum (IV) oxide, platinum dioxide, platinum oxide
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 tsaus no muaj nyob hauv khw. Cov oxide nws tus kheej tsis yog ib qho catalyst nquag, tab sis nws ua haujlwm tom qab raug hydrogen ces nws hloov mus ua platinum dub, uas yog lub luag haujlwm rau cov tshuaj tiv thaiv.
1. Hydrogenation catalyst, tsim nyog rau ob chav bond, triple bond, aromatic hydrocarbon, carbonyl, nitrile, nitro txo.
2.Cov ntaub ntawv zoo heev rau kev nqus hydrogen.
3. Kev tiv thaiv nrog qhov tsis tshua muaj nqi tiv thaiv hauv kev lag luam hluav taws xob.
4. Cov ntaub ntawv raw rau cov khoom xws li potentiometer thiab cov ntaub ntawv tuab zaj duab xis rau kev lag luam hluav taws xob.
