Daim ntawv thov ntawm scandium stabilized cerium zirconium composite hmoov:
Kev siv tseem ceeb ntawm scandium stabilized cerium-zirconium composite hmoov yog raws li cov khoom siv electrolyte ntawm cov khoom oxide roj cell, uas muaj cov hluav taws xob zoo tshaj plaws ntawm qhov nruab nrab thiab qis. Khoom oxide roj cell (SOFC) muaj cov khoom siv sab nraud thiab cov oxidant, cathode, anode thiab electrolyte. Raws li lub zog txuag thiab huv si, nws yog lub npe hu ua roj teeb ntsuab nyob rau hauv lub xyoo pua 21st. Feem ntau, lub zog hloov dua siab tshiab ntawm cov roj hlwb yog 50% -70%, thaum qhov kev ua tau zoo ntawm SOFC nrog cov txheej txheem cogeneration tuaj yeem siab txog 80%. Nws tuaj yeem siv tau los ua lub chaw nres tsheb fais fab hauv pej xeem xws li loj hauv nruab nrab fais fab mov thiab nruab nrab tus nqi sib koom me me hauv tsev cogeneration. Tsis tas li ntawd, nws kuj tseem siv tau los ua lub zog hluav taws xob xws li lub nkoj fais fab mov thiab tsheb thauj khoom fais fab.
Lub hauv paus ntsiab lus ntawm kev ua hauj lwm ntawm lub tsheb tso pa purification catalyst yog ua kom siv cov pa seem hauv cov pa tso pa thiab qhov kub siab dua kom ua tiav cov oxidation-txo cov tshuaj tiv thaiv ntawm cov catalyst nto los hloov cov teeb meem tshuaj Co, hydrocarbons (HC) thiab nitrogen. oxides (NOx) rau hauv uas tsis yog-tshuaj lom CO2, H2O thiab N2, thiaj li txo cov pa phem rau ib puag ncig. Raws li cov khoom siv nyob rau hauv lub tsheb tso pa purification catalyst, oxygen cia khoom plays lub luag hauj lwm nyob rau hauv purifying tsheb tso pa roj, cerium-zirconium composite hmoov yog tsuas yog siv raws li cov active khoom ntawm tsheb pa purification catalyst nyob rau hauv thaum ntxov theem. Cerium-zirconium oxygen cia cov ntaub ntawv tam sim no yog cov khoom tseem ceeb ntawm cov txheej txheem ua haujlwm vim nws cov pa oxygen zoo thiab tso tawm cov yam ntxwv, nws tau siv dav hauv tsheb tso pa purification catalyst ua tiav. Daim ntawv thov ntawm cerium-zirconium oxygen cia cov ntaub ntawv tuaj yeem tsis tsuas yog txhim kho cov catalytic kev ua tau zoo ntawm cov catalyst, xws li txo qhov kub ntawm qhov hluav taws kub, txhim kho cov kav ntev ntawm cov catalyst, tab sis kuj ua rau kom muaj txiaj ntsig ntawm cov hlau muaj txiaj ntsig thiab txo cov nqi ntawm cov hlau tseem ceeb. ntawm lub catalyst. Txawm li cas los xij, thaum cerium-zirconium oxygen cia cov ntaub ntawv siv los ua kom huv lub tsheb, lawv qhov kev ruaj ntseg ntawm 1000 degree tsis zoo, thiab lub peev xwm ntawm cov pa roj redox tsis tuaj yeem ua tau raws li cov kev cai uas twb muaj lawm ntawm kev tiv thaiv ib puag ncig.
HNRE tau tsim ib hom tshiab ntawm scandium stabilized cerium-zirconium composite hmoov, uas feem ntau yog zirconium, cerium, scandium thiab oxygen, thiab lub ntsiab theem yog cubic theem. Lub active tivthaiv ntawm cov pa cia khoom nyob rau hauv lub scandium stabilized cerium-zirconium composite hmoov yog CeO. Los ntawm embedding Zr (0.084nm) thiab Sc (0.0745nm) nrog lub vojvoog tsawg dua Ce (0.097nm) rau hauv CeO lattice, lub cell ntim yuav me dua, qhov lattice distortion yog tshwm sim, lub zog ua kom lub zog ntawm oxygen ion diffusion yog txo, cov pa mus rau hauv lub lattice oxygen yog txhim kho, thiab lub peev xwm redox yog txhim kho. Nyob rau tib lub sijhawm, Zr tseem yuav ua rau kev tsim cov khoom siv lead ua tsis zoo, uas tuaj yeem txhim kho cov khoom redox zoo dua. Yog li, lub cubic theem hloov kub ntawm scandium stabilized cerium zirconium puas hmoov yuav raug txo kom tsawg, thiab qhov kub siab thermal stability ntawm scandium stabilized cerium zirconium puas hmoov tuaj yeem txhim kho.
Lub scandium ruaj khov cerium zirconium composite hmoov tsim los ntawm HNRE tuaj yeem daws cov teeb meem uas cov khoom siv oxygen hauv lub catalyst ntawm lub tsheb tso pa roj purification hauv cov duab ua ntej yog yooj yim rau decompose nws tus kheej ntawm qhov kub thiab txias, tsis muaj peev xwm REDOX thiab cov pa roj purification tsis zoo.
