Nyob rau hauv kev xaiv thiab tsim ntawm cov hlau catalysts, nws yog feem ntau txiav txim siab tias yuav tsum muaj lub zog adaptability thiab spatial adaptability ntawm cov hlau Cheebtsam thiab cov reactant molecules, thiaj li yuav pab txhawb kev ua kom cov tshuaj tiv thaiv molecules. Tom qab ntawd, xav txog kev xaiv cov cocatalysts thiab catalysts uas tsim nyog nrog rau cov txheej txheem kev npaj yuav tsum tau ua, thiab nruj me ntsis tswj cov txheej txheem kev npaj kom tau raws li qhov xav tau cov tshuaj muaj pes tsawg leeg thiab cov qauv ntawm lub cev, suav nrog cov hlau nplej loj thiab kev faib tawm. Nrog rau kev zam ntawm cov hlau muaj txiaj ntsig, hlau catalysts nyob rau hauv lub xeev txo qis heev reactive thiab raug rau oxidation. Rau qhov yooj yim ntawm kev khaws cia thiab kev thauj mus los, cov chaw tsim khoom catalyst feem ntau muab cov khoom lag luam hauv lub xeev oxide (saib cov lus), thiab tus neeg siv tau qhib lossis rov qab mus rau lub xeev hlau thaum siv. Cov txheej txheem thiab cov xwm txheej ntawm kev ua kom muaj zog tseem ceeb heev (saib Catalyst Siv ). Qee cov tuam txhab catalyst kuj tseem muaj qee qhov kev txo qis hlau catalysts rau ammonia synthesis kom luv lub sijhawm pib ntawm tus neeg siv thiab xyuas kom meej cov yam ntxwv ntawm cov catalyst.
