Funda ngokuhlanganiswa nokuguqulwaI-Cerium Oxide Nanomatale
Ukuhlanganiswa kweUCouria NanomativestsKubandakanya ukuhanjiswa kwezulu, ama-coprecipicipicipicipicipicipation, i-hydrothermal, ukuhlanganiswa kwemishini, ukuhlanganiswa kwe-combussion, i-sol gel, i-micro lotion, izindlela ezi-micro kanye nezindlela eziphambili zohlobo, phakathi kwazo ezindleleni eziphambili ze-hydrothesis. Indlela ye-Hydrothermal ibhekwa njengendlela elula, yezomnotho kakhulu, nezengezo. Inselelo enkulu ye-Hydrothermal indlela ukulawula i-nanoscale morphology, edinga ukulungiswa ngokucophelela ukulawula izici zayo.
Ukuguqulwa kwekhaliIngathuthukiswa ngezindlela eziningana: (1) Donsela amanye ama-metal ion ngamanani aphansi noma osayizi abancane e-ceria lattice. Le ndlela ayikwazi ukwenza ngcono ukusebenza kwensimbi oxides ehilelekile, kepha futhi yakha izinto ezintsha ezizinzile ezinezakhiwo ezintsha zomzimba nangamakhemikhali. .I-Cerrium OxideFuthi ingasebenza njengesiphathi sezinsimbi ezihlakazekile njengegolide, iplatinamu, ne-palladium. Ukuguqulwa kwezinto zokwenziwa ze-cerium dioxide ngokuyinhloko ikakhulukazi zisebenzisa izinsimbi zoshintsho, okungavamile i-Alkali / Alkali / izinsimbi zensimbi, nezinsimbi zomhlaba ezingandile, kanye nezinsimbi eziyigugu, ezinomsebenzi ongcono kanye nokuqina okushisayo.
Ukusetshenziswa kweI-Cerrium Oxidenama-composite catalysts
1, ukusetshenziswa kwama-morphologies ahlukene we-ceria
ULaura et al. kubikwa ukuthi ukunqunywa kwezinhlobo ezintathu zemidwebo yesigaba se-ceriarphology, ezihlobene nemiphumela yokushisa kwe-alkali kanye ne-hydrothermal yokushisa yokwelashwa kuya kokugcinaI-CEO2I-Nanosfunducture morphology. Imiphumela ikhombisa ukuthi umsebenzi we-catalytic uhlobene ngqo ne-CE3 + / CE4 + Ratio kanye nokuhlushwa komhlaba we-O Oxygen Wei et al. Ihlanganiswe 3 PT /I-CEO2Ama-Catalysts ane-Carrier Carriers ehlukile (Induku njenge (I-CEO2-R), i-cubic (I-CEO2-C), ne-octahedral (I-CEO2-O), okulungele ikakhulukazi i-oxidation ephansi yokushisa ye-catalytic ye-C2H4. Bian et al. ilungiselele uchungechunge lweI-CEO2 Nanomatadiumnge-rod-delod, cubic, granular, kanye ne-octahedral morphology, futhi uthole ukuthi ama-catalysts alayishweI-CEO2 Nanoparticles(5NI / NPS) ukhombise umsebenzi ophakeme kakhulu we-catalytic kanye nokuqina okungcono kunama-catalysts anezinye izinhlobo zeI-CEO2Ukusekelwa.
I-2.catalytic Devatation yokungcola kwamanzi emanzini
I-Cerrium Oxideiye yaqashelwa njenge-oxidation esebenzayo ye-ozone oxidation esebenza ngokususwa kwamakhompiyutha akhethiwe we-organic. Xiao et al. kutholakale ukuthi ama-pt nanoparticles ahlangana eduze neI-CEO2Endaweni e-Catalyst futhi wasebenzisana ngokuqinile, ngaleyo ndlela wenza ngcono umsebenzi wokubola kwe-Ozone futhi ukhiqize izinhlobo eziningi ze-oxygen ezisebenzayo, ezinomthelela kwi-oxidation of Toluene. UZhang Lanhe nabanye balungiselelweI-CEO2/ Al2o3 Catalysts. I-Doped Metal Oxides ihlinzeka ngesikhala sokuphendula sokusabela phakathi kwamakhompiyutha eziphilayo kanye ne-O3, okuholela ekusebenzeni okuphezulu kwe-catalytic kweI-CEO2/ Al2o3 kanye nokwanda kweziza ezisebenzayo ebusweni be-catalyst
Ngakho-ke, izifundo eziningi zikhombisile lokhoI-Cerrium OxideAma-composite catalysts awakwazi ukuthuthukisa kuphela ukonakala kokungcola okuncane okuphilayo emkhakheni we-catalytic ozone ukwelashwa kwamanzi amdaka, kodwa futhi abe nemiphumela yokuvimbela ama-bromate akhiqizwa ngesikhathi senqubo ye-ozone catalytic. Banamathemba abanzi wohlelo lokusebenza ekwelashweni kwamanzi kwe-ozone.
3, ukucekelwa phansi kwe-catalytic kwezinto eziguquguqukayo ze-organic
I-CEO2, njenge-oxide evamile engajwayelekile
Wang et al. Kwenziwe i-CE mn composite oxphothite nge-morphology ebunjiwe enduneni (CE / mn molar ratio of 3: 7) usebenzisa indlela hydrothermal. Mn ion wadonswa kuI-CEO2Uhlaka lokubuyisela esikhundleni se-CE, ngaleyo ndlela lukhulise ukugcwaliseka kwezikhala zomsebenzi we-oksijini. Njengoba i-CE4 + ithathelwa indawo yi-MN ions, kwakhiwa izikhala zomsebenzi we-oksijini, okuyisizathu somsebenzi wayo ophakeme. Du et al. I-Synthesised MN CE ama-Catalysts esebenzisa indlela entsha ehlanganisa i-redox yezulu kanye nezindlela ze-hydrothermal. Bathola ukuthi isilinganiso se-manganese futhiumrintshiUdlale indima ebalulekile ekwakhekeni kwe-catalyst futhi kuthinte kakhulu ukusebenza kwawo kanye nomsebenzi we-catalytic.Umrintshie-manganeseI-Cerrium OxideUdlala indima ebalulekile e-Adsorption of Toluene, futhi iManganese ikhonjiswe ukuthi idlala indima ebalulekile e-Oxidation of Toluene. Ukuhlanganiswa phakathi kwe-manganese ne-cereyumu kuthuthukisa inqubo yokusabela kwe-catalytic.
I-4.Potocatalystst
ILanga Et al. Ilungiselelwe ngempumelelo ngempumelelo i-CE PR FE-0 @ C kusetshenziswa indlela yendawo yezulu. Umshini othile ukuthi inani le-Droping le-PR, FE, kanye no-C badlala indima ebalulekile kumsebenzi we-photocatalytic. Kwethulwa inani elifanele le-PR, FE, kanye noI-CEO2Ingathuthukisa kakhulu ukusebenza kwe-photocatalytic kwesampula etholwe, ngoba ine-adsorption engcono yokungcola, ukumuncwa ngempumelelo okubonakalayo kokukhanya okubonakalayo, izinga lokudalwa kwamabhendi aphezulu, kanye nezikhala ze-oksijini. Umsebenzi we-photocatalytic othuthukisiwe weI-CEO2-Ama-Nanocomos alungiselelwe yiGanesan et al. Kuthiwa yindawo ethuthukisiwe yendawo, ukuqina kokumunca, i-bandgap emincane, kanye nemiphumela ye-Photoresponse. U-Liu et al. Kutholakale ukuthi i-CE / Como4 Composite Catalyst iyindlela esebenza kahle kakhulu ngenani elingenzeka kohlelo lokusebenza. Petrovic et al. okulungiselelweI-CEO2Ama-Catalysts asebenzisa indlela ejwayelekile yamanje kagesi futhi ayishintshile ngokucindezela okungekho emkhathini okushisayo okudonsa i-plasma ye-corona. Zombili lezi zinto eziguquliwe ze-plasma nezinto ezingekho emthethweni zibonisa ikhono elihle le-catalytic kuzo zombili izinqubo ze-plasma nezinqubo zokuwohloka kwe-photocatalytic.
Ukugcina
Le ndatshana ibukeza ithonya lezindlela ze-synthesis zeI-Cerrium Oxidekwi-marferpelmology eyizinhlayiyana, indima ye-morphology ezinhlakalweni ezingaphezulu kanye nomsebenzi we-catalytic, kanye nomphumela wokusebenzisana kanye nesicelo phakathiI-Cerrium OxidenabakwaDopants nabathwali. Yize ama-catalysts ase-cerrium oxide asekelwe kabanzi futhi asetshenziswe emkhakheni weCatalysis, futhi enze inqubekela phambili enkulu ekuxazululeni izinkinga zemvelo ezinjengokwelashwa kwamanzi, kusesenezinkinga eziningi ezisebenzayo, njengokungacaciI-Cerrium OxideI-morphology kanye nendlela yokulayisha ye-cerium esekelwa ama-catalysts. Ucwaningo olwengeziwe luyadingeka endleleni yokuhlanganiswa kwama-catalysts, ukuthuthukisa umphumela we-synergistic phakathi kwezakhi, nokutadisha inqubo ye-catalytic yemithwalo ehlukene.
