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 cov tshuaj tiv thaiv tshiab, thawj kauj ruam yog ua qhov ntsuas 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, nyob rau hauv cov txheej txheem tshuaj tiv thaiv tiag tiag, cov catalyst yuav raug cua sov mus ntev thiab cov tshuaj tiv thaiv tshuaj, thiab qee qhov kev hloov pauv tsis zoo ntawm lub cev thiab tshuaj lom neeg yuav tshwm sim.
Raws li lub ntsiab lus thiab tus yam ntxwv ntawm catalysts, muaj peb yam tseem ceeb catalyst indicators, As kev ua, xaiv, thiab stability.
