Lub ntsiab kev ua tau zoo ntawm cov khoom muaj txiaj ntsig hlau catalysts
Kev ua:Qhov no yog tus qauv rau kev ntsuas qhov ua tau zoo ntawm noble hlau catalysts. Industrially, nws yog feem ntau qhia raws li tus nqi ntawm cov khoom tau txais ib chav tsev ntim (los yog hnyav) ntawm catalyst ib chav tsev lub sij hawm nyob rau hauv tej yam kev mob.
Selectivity:Qhov no yog hais txog qhov tshwj xeeb ntawm cov hlau loj loj catalyst qhov kev txiav txim; uas yog, nyob rau hauv tej yam kev mob, ib tug tshwj xeeb catalyst accelerates ib tug tshwj xeeb tshuaj tiv thaiv. Selectivity feem ntau yog qhia raws li feem pua ntawm cov molar tooj ntawm cov khoom xav tau tom qab cov tshuaj tiv thaiv rau cov molar tooj ntawm cov reactants.
Kev ruaj ntseg:Qhov no yog hais txog lub peev xwm ntawm cov khoom siv hlau zoo los tswj nws cov haujlwm thiab kev xaiv thaum siv, feem ntau qhia raws li nws lub neej. Qhov kev ua tau zoo ntawm cov catalyst tsis yog tsuas yog nyob ntawm tus yam ntxwv ntawm cov khoom siv hlau (xws li cov qauv hluav taws xob ntawm atoms), tab sis kuj nyob ntawm nws cov qauv siv lead ua, qhov loj me, thaj chaw tshwj xeeb, pore qauv, thiab lub xeev dispersion. Tsis tas li ntawd, cov co-catalyst thiab kev txhawb nqa kuj muaj kev cuam tshuam loj rau cov catalyst kev ua tau zoo.
