Nano ceriani bihendutse kandi bikoreshwa cyaneisi idasanzwehamwe nubunini buto, ingano imwe igabanijwe, hamwe nubuziranenge bwinshi.Kudashonga mumazi na alkali, gushonga gato muri aside.Irashobora gukoreshwa nkibikoresho byo gusya, catalizator, abatwara catalizator (inyongeramusaruro), imashini zikoresha amamodoka, imashini zikoresha ultraviolet, lisansi ya selile electrolytite, ceramique electronique, nibindi. , irashobora kugabanya ubushyuhe bwumucyo wubutaka, kubuza imikurire ya lattice, no kunoza ubucucike bwibumba.Ubuso bunini bwihariye bushobora kuzamura ibikorwa bya catalitiki ya catalizator.Imiterere ihindagurika ya valence itanga uburyo bwiza bwa optoelectronic, bushobora gukopororwa mubindi bikoresho bya semiconductor kugirango bihindurwe, kunoza imikorere yimuka ya fotone, no kunoza ingaruka zifoto yibikoresho.
Byakoreshejwe muburyo bwa UV
Nk’uko ubushakashatsi bubyerekana, urumuri ultraviolet ruri hagati ya 280nm na 320nm rushobora gutera uruhu, gutwika izuba, ndetse na kanseri y'uruhu mu bihe bikomeye.Kwongeramo nanoscale cerium oxyde yo kwisiga birashobora kugabanya ingaruka ziterwa nimirasire ya ultraviolet kumubiri wumuntu.Okiside ya Nano cerium ifite ingaruka zikomeye zo kwinjiza imirasire ya ultraviolet kandi irashobora gukoreshwa nka sisitemu ya ultraviolet yinjira mubicuruzwa nka cosmetike yizuba ryizuba, ikirahure cyimodoka, fibre izuba ryizuba, ibifuniko, plastike, nibindi. kwinjiza urumuri rugaragara, itumanaho ryiza, n'ingaruka nziza zo kurinda UV;Byongeye kandi, gutwika amorphous silicon oxyde kuri cerium oxyde irashobora kugabanya ibikorwa byayo bya catalitiki, bityo bikarinda ibara ryangirika no kwangirika kwamavuta yo kwisiga biterwa nigikorwa cya catalitike ya cerium oxyde.
Byakoreshejwe kuri catalizaires
Mu myaka yashize, hamwe no kuzamura imibereho yabantu, imodoka zimaze kumenyekana mubuzima bwabantu.Kugeza ubu, imodoka ahanini zitwika lisansi.Ibi ntibishobora kwirinda kubyara imyuka yangiza.Kugeza ubu, ibintu birenga 100 byatandukanijwe n’umuriro w’imodoka, muri byo birenga 80 ni ibintu bishobora guteza akaga byatangajwe n’inganda zishinzwe kurengera ibidukikije mu Bushinwa, cyane cyane nka monoxyde de carbone, hydrocarbone, okiside ya azote, ibintu byangiza (PM), n’ibindi , usibye azote, ogisijeni, n’ibicuruzwa byaka nka dioxyde de carbone hamwe n’umwuka w’amazi, ibyo bikaba bitagira ingaruka, ibindi bice byose ni bibi.Kubwibyo, kugenzura no gukemura umwanda w’ibinyabiziga byabaye ikibazo cyihutirwa gukemurwa.
Kubijyanye na catalizike yimodoka, ibyinshi mubisanzwe byakoreshwaga nabantu muminsi yambere byari chromium, umuringa, na nikel, ariko ibibi byabo byari ubushyuhe bukabije bwo gutwika, kwandura uburozi, nibikorwa bibi bya catalitiki.Nyuma, ibyuma byagaciro nka platine, rhodium, palladium, nibindi byakoreshejwe nka catalizator, bifite ibyiza nkigihe kirekire cyo kubaho, ibikorwa byinshi, ningaruka nziza zo kwezwa.Nyamara, kubera igiciro kinini nigiciro cyibyuma byagaciro, usanga nanone bafite uburozi bitewe na fosifore, sulfure, gurş, nibindi, kubiteza imbere bigoye.
Ongeramo nano ceria mubikoresho byo gutunganya ibyuka byimodoka bifite ibyiza bikurikira ugereranije no kongeramo non neria ceria: agace kihariye ubuso bwa nano ceria nini, ubwinshi bwikigero ni kinini, ibirimo umwanda wangiza ni muke, kandi nububiko bwa ogisijeni ni yiyongereye;Nano ceria iri kuri nanoscale, itanga ubuso bwihariye bwubuso bwa catalizator mu kirere cy’ubushyuhe bwinshi, bityo bikazamura cyane ibikorwa bya catalitiki;Nka nyongeramusaruro, irashobora kugabanya urugero rwa platine na rhodium ikoreshwa, igahita ihindura igipimo cya lisansi yumwuka ningaruka za catalitike, kandi igatezimbere ubushyuhe bwumuriro nimbaraga za mashini zitwara.
Bikoreshwa mu nganda zibyuma
Bitewe n'imiterere yihariye ya atome n'ibikorwa, ibintu bidasanzwe by'isi birashobora gukoreshwa nk'inyongeramusaruro mu byuma, ibyuma, ibyuma bya aluminium, nikel, tungsten n'ibindi bikoresho kugira ngo bikureho umwanda, gutunganya ibinyampeke no kunoza imiterere y'ibikoresho, bityo bitezimbere ubukanishi, umubiri ndetse na gutunganya ibintu bya alloys, no kunoza ubushyuhe bwumuriro hamwe no kurwanya ruswa ya alloys.Kurugero, mubikorwa byibyuma, isi idasanzwe nkinyongeramusaruro irashobora kweza ibyuma bishongeshejwe, guhindura morfologiya no gukwirakwiza umwanda hagati yicyuma, gutunganya ingano, no guhindura imiterere nimikorere.Gukoresha nano ceria nkigifuniko ninyongeramusaruro birashobora kunoza okiside ya okiside, kwangirika gushushe, kwangirika kwamazi, hamwe na sulfurizasi yimiterere yubushyuhe bwo hejuru hamwe nibyuma bitagira umwanda, kandi birashobora no gukoreshwa nkudukingirizo twicyuma.
Bikoreshwa mubindi bice
Nano cerium oxyde ifite ubundi buryo bwinshi bukoreshwa, nko gukoresha cerium oxyde ishingiye kuri oxyde nka electrolytite mungirangingo ya lisansi, ishobora kugira umwuka mwinshi uhagije wa ogisijeni itandukanijwe hagati ya 500 ℃ na 800 ℃;Kwiyongera kwa cerium oxyde mugihe cyibirunga bya reberi birashobora kugira ingaruka zihindura kuri reberi;Cerium oxyde nayo igira uruhare runini mubice nkibikoresho bya luminescent nibikoresho bya magneti.
