Phunzirani pa kaphatikizidwe ndi kusinthaCerium oxide nanomatadium
Kapangidwe kaCeria NanomatadiumKuphatikiza mpweya, Coprecial, Hydrothermal, ma synthesical synthesis, syrother synthesis, micro odzola, omwe ndi ma hydrothermal. Njira ya hydrothermal imadziwika kuti ndi njira yosavuta kwambiri, yachuma komanso yowonjezera chabe. Vuto lalikulu la njira ya hydrothermal ndikuwongolera ma nanoscale morphology, yomwe imafunikira kusintha mosamala kuti muchepetse mawonekedwe ake.
Kusintha kwaceiaItha Kulimbikitsidwa kudzera mu njira zingapo: (1) kuyika mitengo ina yachitsulo yokhala ndi mitengo yotsika kapena yocheperako ku Ceria Lalice. Njira iyi silingathe kungosintha makonzedwe achitsulo omwe akukhudzidwa, komanso amapanga zida zatsopano zokhazikika ndi zinthu zatsopano komanso mankhwala. .Cerium OxideItha kutumikiranso ngati chonyamulira chofatsa zitsulo monga golide, platinamu, ndi palladium. Kusintha kwa zinthu zochokera ku Cerium dioxide kumagwiritsanso ntchito zitsulo zosinthira, zosowa za Alkali / Alkali Dziko Lapansi, zitsulo zapadziko lapansi, komanso zitsulo zamtengo wapatali, zomwe zimakhala ndi zolimba.
Kugwiritsa ntchitoCerium Oxidendi othandizira ophatikizika
1, kugwiritsa ntchito ma morfologies osiyanasiyana a Cria
Laura et al. adanenanso kutsimikiza kwa mitundu itatu ya Cefology Gawo, zomwe zikugwirizana ndi Alkalimi ndende komanso hydrothermal chithandizo kutentha mpaka komalizaCEO2nanostructure frology. Zotsatirazi zikuwonetsa kuti ntchito yothandizira imagwirizana mwachindunji ndi CE3 + / CE4 kuthamanga ndi malo osinthira oxygen kutchuka. Wei et al. makesi atatu pt /CEO2Zojambula ndi zonyamula morfologies (ndodo ngati (CEO2-R), cubic (CEO2-C), ndi octahedral (CEO2- Bian et al. Konzani mndandanda waCEO2 nanomatadiumNdi ndodo, cubic, granular, ndi octahedr Morphology, ndipo adapeza kuti othandizira adanyamulaCEO2 nanoparticles.CEO2thandizo.
2.catict kuwonongeka kwa zodetsa m'madzi
Cerium Oxideyadziwika kuti ndi othandizira oxidation ogwiritsira ntchito pochotsa mankhwala opangira zachilengedwe. Xiao et al. adapeza kuti PT nanoparticles akulumikizana ndiCEO2Pa chothandizira komanso cholumikizira zinthu mwamphamvu, potero kukonza zinthu za Ozoni kuwonongeka ndikupanga mitundu yambiri ya okosijeni, omwe amathandizira oxibenation toloene. Zhang Lasa ndi ena adakonzekereratuCEO2/ Al2o3 Catalysts. Ma oxide oxilis amapereka malo omwe achitika pakati pa zopangidwa ndi organic mankhwala ndi o3, zomwe zimapangitsa kuti zikhalepoCEO2/ Al2o3 ndi kuchuluka kwa malo ogwirizira pa chothandizira
Chifukwa chake, maphunziro ambiri awonetsa kutiCerium OxideZojambulajambula sizimangolimbikitsa kuwonongeka kwa zotsetsereka zotsekemera zam'madzi zam'madzi zochizira zinyalala, komanso zimakhalanso ndi zoletsa zam'mawa Ali ndi chiyembekezo chogwiritsira ntchito kugwiritsa ntchito madzi a Ozone.
3, kuwonongeka kwa catalytic kwa osinthika okondwerera
CEO2, monga dziko losowa kwambiri kwa oxide, laphunziridwa kwambiri catalysis chifukwa chosungirako kwa oxygen.
Wang et al. Anasiyitsa a CE MN yopanga oxide ndi morphology (CE / MN) (7) pogwiritsa ntchito njira ya hydrothermal. MN ion iyo idakhazikitsidwa muCEO2chimango chosinthira kusintha kwa CE, potero kukuwonjezera kuchuluka kwa ntchito za oxygen. Monga CE4 + yasinthidwa ndi a Iony, ndalama zambiri za oxygen zimapangidwa, zomwe ndi chifukwa chochitira zinthu zambiri. Du et al. Kuphatikizika kwa MN CE Oxide pogwiritsa ntchito njira yatsopano yophatikiza redox mpweya ndi hydrothermal njira. Adapeza kuti chiwerengero cha manganese ndiceumadasewera mbali yofunika kwambiri pakupanga kwa chothandizira ndi kwakukulu ndikugwira ntchito yake.Ceummu manganeseCerium OxideAmachita mbali yofunika kwambiri mu Adsorption wa Toliene, ndipo manganese awonetsedwa kuti azigwira gawo lofunikira kwambiri m'mafuta. Mgwirizano pakati pa manganese ndi cerium amasintha njira yothandizirana.
4.Photopocatalyst
Sun et al. kukonza bwino CE PR Fe-0 @ C pogwiritsa ntchito njira ya ce. Njira inayake ndikuti kuchuluka kwa PR, Fe, ndi Chyys ndi gawo lofunikira ku Photocatalyc ntchito. Kuyambitsa kuchuluka koyenera kwa pr, Fe, ndi CCEO2Itha kusintha bwino Photocatalytic ya chiwonetserochi, chifukwa kuyankhula bwino kwa zodetsa, kuyankha bwino kwa zodetsa, kuyankha kwamphamvu kwa mabotolo owoneka, komanso ntchito zambiri zamapulogalamu. Ntchito yokwezeka yaCEO2-Go nanocomposites yokonzedwa ndi gaensan et al. Amadziwika kuti ndi malo ophatikizika, kuyamwa mwachangu, ndipo chopapatiza chojambulidwa. Liu et al. anapeza kuti CE / Coudo4 Composite ndi njira yothandiza kwambiri ndi mtengo wogwiritsira ntchito. Petrovic et al. okonzekeraCEO2Zojambulajambula pogwiritsa ntchito njira yamakono yamakono ndikuwasinthira ndi mizere yopanda matenthedwe amlengalenga ku Corona Plasma. Zida zonse ziwiri za plasma zosinthidwa komanso zosavomerezeka zikuwonetsa luso lazinthu la calma komanso protococatalytiction kuwonongeka.
Mapeto
Nkhaniyi imawunikira zomwe zimapangitsa kuti zigwirizane zaCerium OxidePa tinthu tambiri, ntchito ya morphology pamtunda katundu komanso ntchito yothandizira, komanso zotsatira za synergistiction ndikugwiritsa ntchito pakatiCerium Oxidendi okhala ndi onyamula. Ngakhale ma catalys a Cendium Oxide omwe amaphunziridwa ndikugwiritsidwa ntchito m'munda wa catalysis, ndipo achita bwino kwambiri pokwaniritsa chilengedwe monga chithandizo chamadzi, pamakhala zovuta zambiri, monga osamvekaCerium OxideMorphology ndi kutsitsa makina a Crium omwe amathandizidwa ndi othandizira. Kafukufuku wina amafunikira njira ya canchesi ya catalysts, yolimbitsa mphamvu pakati pa zikuluzikulu, ndikuwerenga makina amphatso a katundu wosiyanasiyana.
