I-Cerium oxide, eyaziwa nangokuthi i-ceria, iyinto eguquguqukayo futhi esetshenziswa kabanzi enohlu lwezinhlelo zokusebenza kuzo zonke izimboni ezahlukahlukene. Le nhlanganisela, equkethe i-cerium nomoya-mpilo, inezici eziyingqayizivele ezenza ibe yigugu ngezinhloso ezihlukahlukene.
Ukuhlukaniswa kwe-cerium oxide:
I-Cerium oxide ihlukaniswa njenge-earth metal oxide engavamile, eyingxenye yezakhi ze-lanthanide. Impushana ekhanyayo ephuzi kuya kokumhlophe enokusimama okushisayo okuphezulu kanye nezakhiwo ezinhle kakhulu ze-catalytic. I-cerium oxide ivame ukutholakala ngezindlela ezimbili ezihlukene: i-cerium (III) oxide ne-cerium (IV) oxide. I-Cerium (III) oxide isetshenziswa njenge-catalyst nasekukhiqizeni ingilazi, kuyilapho i-cerium (IV) oxide isetshenziswa ekukhiqizeni izinhlanganisela zokupholisha nanjenge-catalyst ekuphenduleni kwamakhemikhali okuhlukahlukene.
Ukusetshenziswa kwe-cerium oxide:
I-Cerium oxide inezinhlobonhlobo zezicelo ngenxa yezakhiwo zayo eziyingqayizivele. Okunye okuvamile ukusetshenziswa kwe-cerium oxide ukukhiqizwa kweziguquli ze-catalytic zezimoto. Kuyasiza ukunciphisa ukukhishwa okuyingozi ngokuguqula amagesi anobuthi abe izinto eziyingozi kancane. Ngaphezu kwalokho, i-cerium oxide isetshenziswa ekwenzeni ingilazi, njengoba ingathuthukisa izakhiwo ze-optical futhi yandise ukumelana nemisebe ye-UV. Ibuye isetshenziswe njenge-ejenti yokupholisha ingilazi, izitsha zobumba, nezinsimbi, ihlinzeka ngokubushelelezi futhi okukhanyayo.
Ngaphezu kwalokho, i-cerium oxide isetshenziselwa ukukhiqizwa kwamaseli kagesi, lapho isebenza njenge-electrolyte ukuze kube lula ukuguqulwa kwamandla amakhemikhali abe amandla kagesi. Emkhakheni wezokwelapha, i-cerium oxide nanoparticles ibonise amandla okusetshenziswa ezinhlelweni ze-biomedical, njengokulethwa kwezidakamizwa nokuthwebula izithombe. Ukwengeza, i-cerium oxide isetshenziswa ekukhiqizeni ama-phosphors ekukhanyisweni kwe-fluorescent nasekuhlanganiseni izinhlanganisela ezihlukahlukene zezinto eziphilayo.
Sengiphetha, i-cerium oxide iyinto ebalulekile enezinhlelo zokusebenza ezihlukene kuzo zonke izimboni eziningi. Izakhiwo zayo eziyingqayizivele, ezihlanganisa izici ze-catalytic, optical, kanye nezikagesi, ziyenza ibe yingxenye ebalulekile ekukhiqizeni imikhiqizo nobuchwepheshe obuhlukahlukene. Njengoba ucwaningo nentuthuko ku-nanotechnology kanye nesayensi yezinto zokwakha iqhubeka, ukusetshenziswa okungase kube khona kwe-cerium oxide kungenzeka kwande, kuqhubeke kugqamisa ukubaluleka kwayo embonini yesimanje.
