15529-49ft Cov ntsiab lus 10.5% Tris (Tripyenyylphphfphfyresh) Ruthenium (II) Chloride
Kev qhia ua
Cov khoom muaj nuj nqis hlau catalysts yog noble ua tau siv nyob rau hauv kev lag luam tshuaj lom neeg rau lawv lub peev xwm los ua kom nrawm rau cov txheej txheem tshuaj lom neeg. Kub, palladium, platinum, rhodium, thiab nyiaj yog qee cov piv txwv ntawm cov khoom siv hlau. Cov khoom muaj nuj nqis hlau catalysts yog cov uas muaj cov dispogy dispersed nano-nplai cov khoom lag luam zoo li cov pa roj carbon, silica, thiab alumina. Cov catalysts muaj ob peb daim ntawv thov nyob rau ntau yam kev lag luam. Txhua cov nroj tsuag hlau precious muaj cov yam ntxwv tshwj xeeb. Cov catalysts feem ntau yog siv rau cov organic synthesis cov tshuaj tiv thaiv. Yam khoom xws li kev loj hlob xav tau los ntawm kev txhawj xeeb txog qhov kawg, ib qho kev txhawj xeeb ib puag ncig thiab lawv txoj cai cuam tshuam yog tsav tsheb kev loj hlob.
Cov khoom ntawm cov khoom siv hlau hlau catalysts
1.Xav tej yam kev ua ub no thiab xaiv cov nqi ntawm cov khoom siv hlau hauv catalysis
Prepious hlau catalysts muaj nano zoo li dispersed nano-nplai cov hlau loj ntawm cov pa dej siab xws li cov pa roj carbon, silica, thiab alumina. Nano nplai hlau yoojyim yooj yim adsorb hydrogen thiab oxygen nyob rau hauv cov huab cua. Lub hydrogen lossis oxygen yog nquag vim nws cov adsociative adsorption los ntawm D-Electron ntawm cov plhaub ntawm cov khoom muaj nuj nqis mats.
2.Qhov
Cov hlau uas muaj txiaj ntsig yog ruaj khov. Lawv tsis yooj yim tsim oxides los ntawm oxidation. Cov oxides ntawm cov khoom siv hlau uas muaj nqes yog, ntawm qhov tod tes, kuj tsis ruaj khov. Cov khoom muaj peev xwm tsis yooj yim yaj hauv cov kua qaub lossis alkaline. Vim hais tias ntawm siab thermal stability, precious hlau catalyst tau siv tau xws li cov pa tso pa pa roj catalysts.
