Inkcazo kunye neempawu

Inkcazo: I-WNX isebenzisa ubuchwepheshe bokuvelisa obuzenzekelayo obuphambili kwaye isebenzisa izinto ezisemgangathweni ophezulu ukuvelisa umgangatho ophezuluUbungakanani obukhulu beCerium Oxide.

Ezona mpawu:

Ubunyulu obuphezulu:Ubungakanani obukhulu beCerium Oxide

ayinazo izinto ezingcolisayo ezivela kwizinto ezinqabileyo zomhlaba (ezifana nesinyithi, ikhalsiyam, isodiyam), kwaye umxholo wokungcola uphantsi.

Ukunyibilika Okulungileyo:Ubungakanani obukhulu beCerium Oxide

inokunyibilika ngokukhawuleza emanzini nakwii-asidi ezinamandla.

Ukungaguquguquki: Ulawulo olungqongqo lwebhetshi ekuvelisweni kweUbungakanani obukhulu beCerium Oxide

iqinisekisa umgangatho ozinzileyo kwimveliso emikhulu yemizi-mveliso.

Izinto ezibangela ukungasebenzi kakuhle kweshishini leekhemikhali:Ubungakanani obukhulu beCerium Oxide, ngenxa yamandla ayo aphezulu oomatshini kunye nokuzinza, isetyenziswa njengesithwali se-catalyst esibalaseleyo kwii-reactors ezizinzileyo ezifuna ukumelana noxinzelelo oluphezulu okanye impembelelo yokuhamba komoya ngesantya esiphezulu. Ingalayisha ngokufanelekileyo izinyithi ezixabisekileyo (ezifana neplatinum kunye ne-palladium) kwaye isetyenziswa kwiinkqubo ezifana ne-hydrogenation kwiikhemikhali ze-petrochemicals, yandisa kakhulu ubomi benkonzo ye-catalyst. Iimpawu zayo ezizodwa ze-oxygen vacancy defect nazo zenza ukuba idlale indima ebalulekileyo ekucoceni i-vehicle exhaust (ii-catalytic converters ezintathu-way), ikhuthaza ukuguqulwa kwe-carbon monoxide (CO), ii-hydrocarbons (HC), kunye ne-nitrogen oxides (NOx).

Iarhente yokususa iPhosphorus echibini:Ubungakanani obukhulu beCerium Oxide Amasuntswana anokufunxa aze akhuphe ii-ion ze-phosphate emzimbeni wamanzi ngempumelelo, ngaloo ndlela ethintela ukukhula kwe-algae kwaye isombulule ingxaki ye-eutrophication emzimbeni wamanzi. Ubungakanani bamasuntswana bukhulu kakhulu, kwaye ukusebenza kwawo kwe-sedimentation kungcono xa kusetyenziswa emzimbeni wamanzi, okwenza kube lula ukuphinda kubuyekezwe kwaye kuncitshiswe umngcipheko wongcoliseko lwesibini.

Iibhetri kunye nezixhobo zamandla: Kwiiseli zamafutha ze-oxide eziqinileyo (ii-SOFC),Ubungakanani obukhulu beCerium Oxide ingasetyenziswa njengesixhobo se-electrolyte. Uzinzo lwayo oluphezulu lwemida yeenkozo lunceda ukuphucula ukuhanjiswa kwe-ionic kunye nokuqina kokusebenza kwexesha elide kwebhetri. Ukongeza, ingasetyenziswa njengezinto eziluhlaza zokulungiselela ii-alloys zokugcina i-hydrogen ze-electrode engalunganga yeebhetri ze-nickel-hydrogen, okanye ukuguqula izixhobo ze-electrode zebhetri ye-lithium-ion, ngaloo ndlela iphucula ukusebenza kwebhetri ngesakhiwo sayo esizinzileyo.

Izinto ezidityanisiweyo zokwenziwa kweekhemikhali:Ubungakanani obukhulu beCerium Oxide sisixhobo esibalulekileyo sokulungiselela ezinye izinto ezisebenzayo ezisekelwe kwi-cerium (ezifana neetyuwa ze-cerium, i-doped cerium oxide, njl.njl.). Ngokusebenzisa iikhemikhali ezongezelelweyo, ingaguqulwa ibe ziikhompawundi ze-cerium ezineempawu ezithile kunye neempawu, ezisetyenziswa kwiindawo ezifana neeseramikhi ze-elektroniki kunye nezinto zokufunxa i-ultraviolet.
