Inogona kushandiswa sezvinhu zvekupenya, zvinokonzeresa, catalyst carriers (additives), mota inopedza mhepo, ultraviolet absorbers, fuel cell electrolytes, electronic ceramics, etc. Nanoscale ceria inogona kukanganisa zvakananga kushanda kwezvinhu, zvakadai sekuwedzera ultrafine nano ceria kune ceramics. , iyo inogona kuderedza sintering tembiricha yekeramics, inhibit lattice kukura, uye kuvandudza density ye Ceramics. Nzvimbo yakakura yakanangana nepamusoro inogona kuwedzera zvirinani iyo catalytic chiitiko cheiyo catalyst. Iyo yakasiyana-siyana valence zvivakwa zvinoipa yakanakisa optoelectronic zvivakwa, izvo zvinogona kudonhedzwa mune zvimwe semiconductor zvinhu zvekugadzirisa, kuvandudza kushanda kweiyo photon migration, uye kugadzirisa iyo photoexcitation mhedzisiro yezvinhu.
Inoshandiswa kune UV absorption
Zvinoenderana netsvagiridzo, ultraviolet mwenje kubva pa280nm kusvika 320nm inogona kukonzera kutsvuka kweganda, kupiswa nezuva, uye kunyangwe gomarara reganda mumatambudziko akaomarara. Kuwedzera nanoscale cerium oxide kune zvizorwa zvinogona kuderedza kukuvadza kweiyo ultraviolet radiation kumuviri wemunhu. Nano cerium oxide ine simba rakasimba rekunyura pamirayi ye ultraviolet uye inogona kushandiswa se ultraviolet absorber kune zvigadzirwa zvakadai se sunscreen cosmetics, girazi remotokari, sunscreen fibers, coatings, plastiki, etc. Cerium oxide inoshandiswa mu sunscreen cosmetics, iyo isina maitiro. kunyura kwechiedza chinooneka, kutapurirana kwakanaka, uye yakanaka UV kudzivirira maitiro; Uyezve, kuvhara amorphous silicon oxide pacerium oxide kunogona kuderedza kuita kwayo kunobatsira, nekudaro kudzivirira kushanduka uye kuparara kwezvizoro kunokonzerwa necatalytic chiitiko checerium oxide.
Inoshandiswa kune catalysts
Mumakore achangopfuura, nekuvandudzwa kwemararamiro evanhu, motokari dzave dzichinyanya kufarirwa muupenyu hwevanhu. Parizvino, mota dziri kunyanya kupisa peturu. Izvi hazvigoni kudzivisa kugadzirwa kwemagasi anokuvadza. Parizvino, zvinopfuura 100 zvinhu zvakapatsanurwa kubva kumhepo yemotokari, izvo zvinopfuura makumi masere zvinhu zvine ngozi zvakaziviswa neChinese indasitiri yekudzivirira kwezvakatipoteredza, kunyanya kusanganisira kabhoni monoxide, hydrocarbons, nitrogen oxides, particulate matter (PM), nezvimwewo. , kunze kwenitrogen, okisijeni, uye zvigadzirwa zvinopisa zvakadai secarbon dioxide nemhute yemvura, izvo zvisingakuvadzi zvikamu, zvimwe zvese zvinokuvadza. Naizvozvo, kudzora nekugadzirisa kusvibiswa kwemhepo yemotokari rave dambudziko rekukurumidzira kugadziriswa.
Nezve zvinokonzeresa kubuda kwemotokari, simbi zhinji dzaishandiswa nevanhu mumazuva ekutanga dzaive chromium, mhangura, uye nickel, asi zvipingamupinyi zvavo zvaive tembiricha yekupisa, kubatwa nehupfu, uye kusaita basa rekuita. Gare gare, simbi dzinokosha dzakadai seplatinamu, rhodium, palladium, nezvimwewo zvakashandiswa sezvigadziriso, zvine zvakanakira senge hupenyu hurefu, kuita kwepamusoro, uye kunaka kwekuchenesa maitiro. Nekudaro, nekuda kwemutengo wakakwira uye mutengo wesimbi dzinokosha, ivo zvakare vanowanzoita chepfu nekuda kwephosphorus, sarufa, lead, nezvimwe, zvichiita kuti zviome kukurudzira.
Kuwedzera nano ceria kune mota inopedza tsvina yekuchenesa maajenti kune zvinotevera zvakanakira kana zvichienzaniswa nekuwedzera isiri nano ceria: iyo particle chaiyo nzvimbo ye nano ceria yakakura, huwandu hwekupfeka hwakakwira, zvirimo zvetsvina inokuvadza zvakaderera, uye huwandu hwekuchengetedza okisijeni hwakakura. kuwedzera; Nano ceria iri pa nanoscale, inochengetedza nzvimbo yakakwirira yepamusoro yezvinokonzera mumamiriro ekupisa kwepamusoro, nokudaro kuvandudza zvikuru basa rinokurudzira; Sekuwedzera, inogona kuderedza huwandu hweplatinamu uye rhodium inoshandiswa, inogadzirisa otomatiki huwandu hwemafuta emhepo uye catalytic mhedzisiro, uye inovandudza kugadzikana kwekupisa uye simba remagetsi remutakuri.
Inoshandiswa kune indasitiri yesimbi
Nekuda kwechimiro chayo cheatomu uye chiitiko, zvisingawanzo zvinhu zvepasi zvinogona kushandiswa sezvekuwedzera musimbi, simbi yakakandwa, aluminium, nickel, tungsten uye zvimwe zvinhu kubvisa tsvina, kunatsa zviyo nekuvandudza kuumbwa kwezvinhu, nekudaro kuvandudza michina, yemuviri uye. kugadzirisa zvimiro zvealloys, uye kuvandudza kugadzikana kwekupisa uye kusimba kwekupokana kwealloys. Semuenzaniso, muindasitiri yesimbi, zvisingawanzo pasi sezviwedzere zvinogona kuchenesa simbi yakanyungudutswa, kushandura morphology uye kugoverwa kwetsvina pakati pesimbi, kunatsa zviyo, uye kushandura chimiro nekuita. Kushandiswa kwe nano ceria sechifukidzo uye kuwedzera kunogona kuvandudza kupikisa kwe oxidation, kupisa kunopisa, kupisa kwemvura, uye sulfurization zvinhu zvepamusoro-tembiricha alloys uye simbi isina tsvina, uye inogonawo kushandiswa seinoculant ye ductile iron.
Inoshandiswa kune mamwe maitiro
Nano cerium oxide ine zvimwe zvakawanda zvinoshandiswa, zvakadai sekushandisa cerium oxide based composite oxides se electrolytes mumafuta emafuta, anogona kuva nepamusoro zvakakwana okisijeni dissociation ikozvino density pakati 500 ℃ uye 800 ℃; Kuwedzerwa kwecerium oxide panguva yevulcanization process yerubha inogona kuve neimwe shanduko yekuchinja pane rabha; Cerium oxide inoitawo basa rakakosha muminda senge luminescent zvinhu uye magineti zvinhu.
