CAS 12135-22-7 hlau ntsiab lus 75.78% palladium(ii) hydroxide
Taw qhia
Precious hlau catalysts yog cov hlau zoo uas siv dav hauv kev lag luam tshuaj vim lawv muaj peev xwm ua kom cov txheej txheem tshuaj lom neeg.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 tus muaj nuj nqis hlau catalyst muaj cov yam ntxwv tshwj xeeb.Cov catalysts feem ntau yog siv rau cov organic synthesis cov tshuaj tiv thaiv.Cov xwm txheej xws li kev xav tau los ntawm cov khoom siv kawg, kev txhawj xeeb ntawm ib puag ncig thiab lawv qhov cuam tshuam raws li txoj cai yog ua rau kev loj hlob ntawm kev lag luam.
Properties ntawm precious 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 muaj txiaj ntsig zoo tau siv los ua cov pa roj purification catalysts automotive.
