Qhov zoo tshaj plaws-muag catalyst CAS 18497-13-7 nrog cov ntsiab lus hlau ntawm 37.7% chloroplatinic acid hexahydrate
Taw qhia
Precious hlau catalysts yog cov hlau zoo uas siv dav hauv kev lag luam chemical vim lawv lub peev xwm los ua kom cov txheej txheem tshuaj.Kub, palladium, platinum, rhodium, thiab nyiaj yog qee qhov piv txwv ntawm cov hlau muaj txiaj ntsig.Precious hlau catalysts yog cov uas muaj cov dispersed nano-scale precious hlau hais nyob rau hauv ib tug high deg cheeb tsam xws li carbon, silica, thiab alumina.Cov catalysts no muaj ntau daim ntawv thov hauv ntau yam kev lag luam.Txhua yam khoom muaj nqi hlau catalyst muaj cov yam ntxwv tshwj xeeb.Cov catalysts feem ntau yog siv rau cov organic synthesis cov tshuaj tiv thaiv.Cov yam ntxwv xws li kev xav tau loj hlob los ntawm cov khoom siv kawg, kev txhawj xeeb ntawm ib puag ncig thiab lawv qhov cuam tshuam raws li txoj cai yog tsav kev lag luam loj hlob.
Cov khoom muaj txiaj ntsig zoo ntawm cov hlau catalysts
1.Kev ua haujlwm siab thiab xaiv cov hlau muaj txiaj ntsig hauv catalysis
Precious hlau catalysts muaj xws li dispersed nano-scale precious hlau hais nyob rau hauv kev txhawb nqa nrog high deg cheeb tsam xws li carbon, silica, thiab alumina.Cov nano nplai hlau hais tau yooj yim adsorb hydrogen thiab oxygen hauv qhov chaw.Cov hydrogen los yog oxygen yog nquag heev vim nws dissociative adsorption los ntawm d-electron tawm ntawm lub plhaub ntawm precious hlau atoms.
2. Kev ruaj ntseg
Cov hlau muaj txiaj ntsig zoo ruaj khov.Lawv tsis yooj yim tsim oxides los ntawm oxidation.Cov oxides ntawm cov hlau tseem ceeb yog, ntawm qhov tod tes, kuj tsis ruaj khov.Cov hlau zoo nkauj tsis yooj yim yaj hauv cov kua qaub lossis alkaline.Vim tias muaj kev ruaj ntseg siab, cov hlau tseem ceeb catalyst tau siv los ua cov pa roj purification catalysts automotive.
