Cerium oxide, tseem hu ua nano cerium oxide (CeO2), yog ntau yam khoom siv nrog ntau yam kev siv. Nws cov khoom tshwj xeeb ua rau nws muaj txiaj ntsig zoo hauv ntau qhov kev lag luam, los ntawm hluav taws xob mus rau kev kho mob. Daim ntawv thov ntawm nano cerium oxide tau txais kev saib xyuas tseem ceeb vim nws lub peev xwm los hloov pauv ntau lub teb.
Ib qho ntawm cov kev siv tseem ceeb ntawm nano cerium oxide yog nyob rau hauv lub tshav pob ntawm catalysis. Nws yog dav siv los ua catalyst nyob rau hauv ntau yam txheej txheem tshuaj, suav nrog automotive catalytic converters. Qhov chaw siab tshaj plaws thiab lub peev xwm ntawm cov pa oxygen ntawm nano cerium oxide ua rau nws muaj txiaj ntsig zoo rau kev txo qis cov pa phem los ntawm cov tsheb thiab cov txheej txheem kev lag luam. Tsis tas li ntawd, nws yog siv nyob rau hauv zus tau tej cov hydrogen thiab raws li ib tug catalyst nyob rau hauv cov dej-gas hloov cov tshuaj tiv thaiv.
Hauv kev lag luam hluav taws xob, nano cerium oxide yog siv hauv kev tsim cov khoom siv polishing rau cov khoom siv hluav taws xob. Nws cov khoom abrasive ua rau nws yog cov khoom siv zoo tshaj plaws rau polishing iav, semiconductors, thiab lwm yam khoom siv hluav taws xob. Tsis tas li ntawd, nano cerium oxide tau muab tso rau hauv kev tsim cov roj hlwb thiab cov khoom siv hluav taws xob oxide, uas nws ua haujlwm raws li cov khoom siv electrolyte vim nws cov ionic conductivity siab.
Hauv kev saib xyuas kev noj qab haus huv, nano cerium oxide tau pom cov lus cog tseg hauv ntau daim ntawv thov biomedical. Nws tau raug tshawb fawb txog nws cov peev xwm siv hauv kev xa tshuaj, nrog rau kev kho mob ntawm cov kab mob neurodegenerative. Nws cov khoom antioxidant ua rau nws yog ib tus neeg sib tw rau kev tawm tsam oxidative kev nyuaj siab thiab mob hauv lub cev.
Ntxiv mus, nano cerium oxide tab tom nrhiav kev siv hauv kev kho ib puag ncig, tshwj xeeb hauv kev tshem tawm cov hlau hnyav los ntawm cov dej tsis huv thiab av. Nws lub peev xwm los adsorb thiab neutralize cov pa phem ua rau nws muaj txiaj ntsig zoo hauv kev daws teeb meem ib puag ncig.
Hauv kev xaus, daim ntawv thov ntawm nano cerium oxide (CeO2) nthuav dav thoob plaws ntau lub lag luam, los ntawm catalysis thiab electronics mus rau kev kho mob thiab kev kho ib puag ncig. Nws cov khoom tshwj xeeb thiab ntau yam xwm txheej ua rau nws muaj txiaj ntsig zoo nrog lub peev xwm los tsav kev tsim kho tshiab thiab kev nce qib hauv ntau yam. Raws li kev tshawb fawb thiab kev tsim kho hauv nanotechnology txuas ntxiv mus, cov ntawv thov ntawm nano cerium oxide yuav tsum nthuav dav, ntxiv rau nws qhov tseem ceeb hauv kev tsim lub neej yav tom ntej ntawm kev siv tshuab thiab kev lag luam.
