Cov tshuaj tiv thaiv catalytic muaj plaub yam ntxwv tseem ceeb uas tuaj yeem muab tau los ntawm kev txhais thiab tseem ceeb rau kev nkag siab txog kev ua haujlwm ntawm catalysts.
1. Catalysts tsuas tuaj yeem ceev cov tshuaj tiv thaiv uas tuaj yeem ua rau thermodynamically. Thaum yuav tsum muaj cov tshuaj tiv thaiv kab mob tshiab, thawj kauj ruam yog los ua qhov ntsuas kub ntawm cov tshuaj tiv thaiv kom pom tias nws puas muaj cov tshuaj tiv thaiv thermodynamically.
2. Lub catalyst tsuas tuaj yeem ceev cov tshuaj tiv thaiv kom sib npaug, thiab tsis tuaj yeem hloov txoj haujlwm sib npaug (sib npaug tsis tu ncua) ntawm cov tshuaj tiv thaiv.
3. Lub catalyst muaj selectivity rau cov tshuaj tiv thaiv, thaum cov tshuaj tiv thaiv tej zaum yuav muaj ntau tshaj ib tug sib txawv kev taw qhia, lub catalyst tsuas accelerates ib tug ntawm lawv, thiab cov tshuaj tiv thaiv tus nqi thiab selectivity yog unified.
4. Lub neej ntawm cov catalyst. Catalysts tuaj yeem hloov tus nqi ntawm cov tshuaj tiv thaiv, thiab qhov zoo tshaj plaws catalyst tsis hloov los ntawm cov tshuaj tiv thaiv. Txawm li cas los xij, hauv cov txheej txheem tshuaj tiv thaiv tiag tiag, cov catalyst yuav raug rau lub sijhawm ntev - cua sov thiab tshuaj lom neeg cov tshuaj tiv thaiv, thiab qee qhov kev hloov pauv tsis zoo ntawm lub cev thiab tshuaj lom neeg yuav tshwm sim.
Raws li cov ntsiab lus thiab cov yam ntxwv ntawm cov catalysts, muaj peb yam tseem ceeb catalyst ntsuas: kev ua, kev xaiv, thiab kev ruaj ntseg.
