Dej huv yog qhov tseem ceeb rau lub neej—tab sis muaj ntau yam kuab paug tsis kam kho li niaj zaus. Niaj hnub no, cov tshuaj catalysts tau dhau los ua cov phab ej tsis muaj npe nrov ntawm kev kho dej: lawv ua kom cov tshuaj lom neeg ua haujlwm sai dua, rhuav tshem cov kuab paug, thiab hloov cov dej qias neeg mus ua dej nyab xeeb—yam tsis tau siv tag hauv cov txheej txheem.
Thoob plaws ntiaj teb, cov chaw kho dej vam khom cov thev naus laus zis catalytic kom tshem tawm cov hlau hnyav, cov tshuaj lom organic, tshuaj tua kab, cov xim, tshuaj tua kab mob, thiab cov pa phem me me uas cov lim dej ib txwm tsis tuaj yeem ntes tau.
Cov Catalysts Ua Haujlwm Li Cas Hauv Kev Kho Dej
Cov tshuaj catalysts ua haujlwm ua cov tshuaj txhawb zog. Lawv txo qis lub zog uas xav tau los rhuav tshem lossis hloov cov tshuaj phem. Hauv cov txheej txheem oxidation siab heev (AOPs) - cov txheej txheem ntxuav dej muaj zog tshaj plaws - cov tshuaj catalysts ua haujlwm nrog ozone, hydrogen peroxide, lossis lub teeb los tsim cov pa oxygen uas muaj zog heev. Cov hom tsiaj no sai sai rhuav tshem txawm tias cov pa phem uas tawv ncauj, tsis lwj mus ua dej tsis muaj teeb meem thiab carbon dioxide.
Cov khoom siv catalyst feem ntau suav nrog titanium dioxide (TiO₂), activated alumina, ceramic-supported metals, metal-organic frameworks (MOFs), thiab nano-structured metals xws li hlau, tooj liab, thiab manganese. Ntau cov catalysts ruaj khov heev, siv tau dua, thiab pheej yig.
Cov Kev Siv Tseem Ceeb ntawm Catalysts hauv Kev Kho Dej
Kev puas tsuaj ntawm cov dej khib nyiab hauv kev lag luam: Cov tshuaj catalysts rhuav tshem cov xim los ntawm cov chaw tsim khoom textile, cov tshuaj los ntawm kev tsim tshuaj, thiab cov kuab tshuaj los ntawm kev tsim khoom.
Kev tshem tawm cov tshuaj tua kab mob thiab tshuaj tua kab: Catalytic oxidation tshem tawm cov micro-pollutions uas tshwm sim uas hem cov ecosystem thiab tib neeg kev noj qab haus huv.
Kev tua kab mob yam tsis muaj cov khoom phom sij: Cov txheej txheem catalytic tua cov kab mob thiab cov kab mob kom muaj kev nyab xeeb, tsis zoo li qee txoj kev ib txwm muaj uas tsim cov khoom seem txaus ntshai.
Kev tshem tawm cov hlau hnyav: Cov catalysts txhawb nqa hloov cov hlau lom mus rau hauv cov qauv tsis muaj kev phom sij lossis ntes lawv kom yooj yim sib cais.
Kev tshem tawm cov sulfur thiab kev tshem tawm cov xim: Cov tshuaj catalysts ua kom cov dej huv sai sai los ntawm kev tshem tawm cov xim, ntxhiab tsw, thiab cov pa phem uas muaj sulfur.
Vim li cas cov Catalysts yog yav tom ntej ntawm kev kho dej
Kev kho dej catalytic muaj cov txiaj ntsig zoo:
Kev ua haujlwm zoo txawm tias nyob rau hauv qhov tsawg concentration ntawm cov pa phem
Kev teb ceev ceev
Muaj peev xwm kho cov khib nyiab uas tsis lwj tau
Kev ua haujlwm zoo rau ib puag ncig
Lub neej ua haujlwm ntev thiab tus nqi ua haujlwm qis
Vim muaj dej tsawg zuj zus thiab muaj cov cai ib puag ncig nruj dua, cov tshuaj catalysts tsis yog xaiv tau lawm - lawv yog qhov tsim nyog.
Saib Mus Tom Ntej
Cov kws tshawb fawb txuas ntxiv tsim cov tshuaj catalysts ntse dua, ntsuab dua, thiab muaj zog dua. Cov tshuaj catalysts, nano-catalysts, thiab cov tshuaj catalysts bio-based uas tau txais kev txhawb nqa ua rau kev kho dej huv dua, pheej yig dua, thiab ruaj khov dua.
Hauv lub hom phiaj thoob ntiaj teb los muab dej haus huv thiab tiv thaiv ib puag ncig, cov tshuaj ua kom lub cev tsis yog cov khoom siv xwb - lawv yog cov kev daws teeb meem hloov pauv.
