Catalytic hom
Catalysis tuaj yeem faib ua hom hauv qab no
1 homogeneous catalysis. Catalyst thiab reactants yog txhua tus nyob rau hauv tib theem ntawm catalysis, xws li homogeneous acid-puag catalysis, homogeneous complex catalysis. Homogeneous catalysis yog feem ntau nqa tawm hauv theem ua kua. Cov chaw nquag ntawm cov homogeneous catalysts yog cov homogeneous, nrog kev xaiv ntau dua thiab muaj kev cuam tshuam tsawg dua sab, tab sis cov catalysts nyuaj rau cais, rov ua dua thiab tsim dua tshiab.
2 heterogeneous catalysis. Catalysis tshwm sim ntawm qhov kev sib tshuam ntawm ob theem. Feem ntau cov catalyst yog cov khoom ntxeem tau thiab cov reactants yog kua lossis roj. Nyob rau hauv qhov kev hloov kho heterogeneous catalytic, cov khoom lag luam catalyst ua rau adsorbs cov tshuaj tiv thaiv reactive molecules, ua kom lub zog reactive lwg me me, txo qis kev ua kom lub zog ntawm cov tshuaj tiv thaiv, thiab ua kom nrawm ua tiav. Qhov saum npoo ntawm cov khoom tsim tawm tsis sib npaug, thiab tsuas yog ib feem ntawm cov kis tau zoo adsorbs cov tshuaj tiv thaiv reactant molecules, uas yog hu ua lub chaw nquag. Feem ntau ntawm cov catalysis hauv kev tsim khoom lag luam zwm rau heterogeneous catalysis.
3 biocatalysis. Kev hloov pauv catalytic nqa tawm los ntawm enzyme hauv ib yam muaj sia. Lub catalytic kev ua ntawm lub enzyme muaj cov yam ntxwv ntawm kev xaiv siab, siab catalytic kev ua si thiab cov mob sib cuam tshuam me, tab sis nws zoo heev cuam tshuam los ntawm qhov kub, pH tus nqi hauv kev daws, ionic lub zog thiab lwm yam.
4 tsis siv neeg catalysis. Self-catalysis ntawm cov tshuaj tiv thaiv cov khoom. Hauv qee qhov kev cuam tshuam, cov khoom lag luam lossis kev nruab nrab ntawm qee cov tshuaj tiv thaiv muaj qhov ua haujlwm catalytic uas tso cai rau cov tshuaj tiv thaiv kom nrawm nrawm dhau tom qab ncua sij hawm. Autocatalysis yog ib qho ntawm cov kev mob tsim nyog rau cov tshuaj oscillations.
