Nano ceriaishibhile futhi isetshenziswa kabanzii-oxide yomhlaba engavamilengosayizi wezinhlayiyana ezincane, ukusatshalaliswa kosayizi wezinhlayiyana ezifanayo, nokuhlanzeka okuphezulu. Ayincibiliki emanzini ne-alkali, incibilika kancane ku-asidi. Ingasetshenziswa njengezinto zokupholisha, ama-catalysts, ama-catalyst carriers (additives), izinto zokudonsa umoya wezimoto, izibambisi ze-ultraviolet, ama-electrolyte amaseli kaphethiloli, izitsha zobumba zikagesi, njll. I-Nanoscale ceria ingathinta ngokuqondile ukusebenza kwezinto, njengokwengeza i-ultrafine nano ceria kuma-ceramics. , okunganciphisa izinga lokushisa le-sintering le-ceramics, livimbele ukukhula kwe-lattice, futhi lithuthukise ukuminyana kwezitsha zobumba. Indawo enkulu ethile ingathuthukisa kangcono umsebenzi we-catalyst we-catalyst. Izakhiwo zayo ze-valence eziguquguqukayo ziyinikeza izici ezinhle kakhulu ze-optoelectronic, ezingafakwa kwezinye izinto zokwakha ze-semiconductor ukuze zilungiswe, kuthuthukiswe ukusebenza kahle kokufuduka kwe-photon, kanye nokwenza ngcono umphumela we-photoexcitation wento.
Kusetshenziswa ekumunceni kwe-UV
Ngokocwaningo, ukukhanya kwe-ultraviolet kusuka ku-280nm kuya ku-320nm kungabangela ukushuka kwesikhumba, ukushiswa yilanga, ngisho nomdlavuza wesikhumba ezimeni ezinzima. Ukwengeza i-nanoscale cerium oxide ezimonyoni kunganciphisa ukulimala kwemisebe ye-ultraviolet emzimbeni womuntu. I-Nano cerium oxide inomphumela oqinile wokumunca emisebeni ye-ultraviolet futhi ingasetshenziswa njengesimunyi se-ultraviolet emikhiqizweni efana nezimonyo zokuvikela ilanga, ingilazi yemoto, imicu ye-sunscreen, ama-coatings, amapulasitiki, njll. I-Cerium oxide isetshenziswa kuzimonyo zokuvikela ilanga, ezingenasici. ukumuncwa kokukhanya okubonakalayo, ukudluliswa kahle komshini, nomphumela omuhle wokuvikela i-UV; Ngaphezu kwalokho, ukumboza i-amorphous silicon oxide ku-cerium oxide kunganciphisa umsebenzi wayo we-catalytic, ngaleyo ndlela kuvimbele ukuguquguquka nokonakala kwezimonyo okubangelwa umsebenzi we-catalytic we-cerium oxide.
Kufakwe kuma-catalysts
Eminyakeni yamuva nje, ngokuthuthuka kwezinga lokuphila kwabantu, izimoto ziye zanda ezimpilweni zabantu. Njengamanje, izimoto zishisa kakhulu uphethiloli. Lokhu akukwazi ukugwema ukukhiqizwa kwamagesi ayingozi. Njengamanje, izinto ezingaphezu kwe-100 ziye zahlukaniswa ne-exhaust yemoto, okungaphezu kuka-80 okuyizinto eziyingozi ezimenyezelwe imboni yokuvikela imvelo yaseShayina, ikakhulukazi okuhlanganisa i-carbon monoxide, ama-hydrocarbon, ama-nitrogen oxides, i-particulate matter (PM), njll. , ngaphandle kwe-nitrogen, umoya-mpilo, nemikhiqizo evuthayo efana ne-carbon dioxide nomhwamuko wamanzi, okuyizingxenye ezingenabungozi, zonke ezinye izakhi ziyingozi. Ngakho-ke, ukulawula nokuxazulula ukungcoliswa kwegesi yemoto sekuyinkinga ephuthumayo okufanele ixazululwe.
Ngokuphathelene nezinto ezikhipha umoya wezimoto, izinsimbi eziningi ezivamile ezazisetshenziswa abantu ezinsukwini zakuqala kwakuyi-chromium, ithusi, ne-nickel, kodwa izithiyo zazo kwakuyizinga lokushisa eliphezulu lokuthungela, ukungenwa ushevu, kanye nomsebenzi ongemuhle we-catalytic. Kamuva, izinsimbi eziyigugu ezifana ne-platinum, i-rhodium, i-palladium, njll. zasetshenziswa njengama-catalysts, anezinzuzo ezifana nokuphila isikhathi eside, umsebenzi ophezulu, nomphumela omuhle wokuhlanza. Kodwa-ke, ngenxa yentengo ephakeme kanye nezindleko zezinsimbi eziyigugu, nazo zijwayele ukudliwa ubuthi ngenxa ye-phosphorus, isulfure, umthofu, njll, okwenza kube nzima ukukhuthaza.
Ukwengeza i-nano ceria kuma-ejenti okuhlanza imfucumfucu yezimoto kunezinzuzo ezilandelayo uma kuqhathaniswa nokwengeza i-non-nano ceria: indawo ethile yezinhlayiyana ethile ye-nano ceria inkulu, inani lokumboza liphezulu, okuqukethwe kokungcola okuyingozi kuphansi, namandla okugcina umoya-mpilo anda; I-Nano ceria ikwi-nanoscale, iqinisekisa indawo ethile ephezulu ye-catalyst endaweni yokushisa ephezulu, ngaleyo ndlela ithuthukise kakhulu umsebenzi we-catalytic; Njengesengezo, inganciphisa inani le-platinum ne-rhodium esetshenzisiwe, ilungise ngokuzenzakalelayo isilinganiso sikaphethiloli womoya kanye nomphumela we-catalytic, futhi ithuthukise ukuzinza okushisayo namandla emishini yesithwali.
Kusetshenziswa embonini yensimbi
Ngenxa yesakhiwo sawo esikhethekile se-athomu kanye nomsebenzi, izakhi zomhlaba ezingavamile zingasetshenziswa njengezithasiselo zensimbi, insimbi ekhonjiwe, i-aluminium, i-nickel, i-tungsten nezinye izinto zokuqeda ukungcola, ukucwenga okusanhlamvu kanye nokuthuthukisa ukwakheka kwezinto, ngaleyo ndlela kuthuthukiswe imishini, ngokomzimba kanye ukucubungula izakhiwo zama-alloys, kanye nokwenza ngcono ukuzinza okushisayo nokumelana nokugqwala kwama-alloys. Isibonelo, embonini yensimbi, umhlaba ongavamile njengezithasiselo ungahlanza insimbi encibilikisiwe, uguqule imo kanye nokusatshalaliswa kokungcola phakathi nendawo yensimbi, ucwenge okusanhlamvu, futhi uguqule isakhiwo nokusebenza. Ukusetshenziswa kwe-nano ceria njenge-coating kanye nesengezo kungathuthukisa ukumelana ne-oxidation, ukugqwala okushisayo, ukugqwala kwamanzi, kanye nezakhiwo ze-sulfurization zama-alloys okushisa aphezulu kanye nensimbi engagqwali, futhi ingasetshenziswa njenge-inoculant ye-ductile iron.
Kusetshenziswa kwezinye izici
I-Nano cerium oxide inokunye ukusetshenziswa okuningi, okufana nokusebenzisa ama-oxide ayinhlanganisela asuselwa ku-cerium oxide njengama-electrolyte kumaseli kaphethiloli, angaba nomthamo wamanje wokuhlukaniswa komoya ophezulu owanele phakathi kuka-500 ℃ no-800 ℃; Ukwengezwa kwe-cerium oxide phakathi nenqubo ye-vulcanization yenjoloba kungaba nomthelela othile wokuguqula ku-rubber; I-Cerium oxide nayo idlala indima ebalulekile emikhakheni efana ne-luminescent materials nezinto zikazibuthe.
