Funda kwi-synthesis kunye nokuguqulwaI-cerium oxideneals
I-synthesis yeI-Carland AnomasutialsKubandakanya ukuqina, ukulungiselela, i-hydrothermal, umatshini we-synthesical synthesi, i-SOT Gel, i-Micro Gel, i-Micro Gel, iindlela zePynthesis, phakathi kweendlela eziphambili zeSynthesis. Indlela ye-hydrothermal ithathwa njengeyona ndlela ilula, eyona meko yoqoqosho, kunye nendlela engathethekiyo. Umngeni ophambili wendlela ye-hydrothermal kukulawula i-nanoscaley morphology, efuna uhlengahlengiso ngononophelo ukulawula iimpawu zayo.
Ukutshintsha kwei-ciariainokuphuculwa ngeendlela ezininzi: (1) Ukucola ezinye ii-ion zentsimbi ngamaxabiso asezantsi okanye ubungakanani abancinci kwi-chice. Le ndlela ayinakuphucula ukwenziwa kwentsebenzo yee-oxidee zentsimbi ebandakanyekileyo, kodwa ikwazenzele izinto ezizinzileyo ezinamachaphaza amatsha omzimba kunye neekhemikhali. .I-cerium oxideIngasebenza njengesixhobo sokusasaza izinyithi ezifana negolide, iplatinam, kunye ne-pilladium. Ukuguqulwa kwezinto ezisekwe kwi-cerium diokside ikakhulu zisebenzisa iintsimbi zothungelwano, iAlkali yomhlaba, iAlkali yomhlaba, inqabile emhlabeni, kunye neentsimbi ezixabisekileyo, ezona zinto zixabisekileyo zozinzo.
Ukusetyenziswa kweI-cerium oxidekunye neCatalysts
1, Ukusetyenziswa kwe-morphologues eyahlukeneyo yeCiria
I-Laura et al. Uxele ukumiselwa kweentlobo ezintathu zeCiria Morjerams, ezichaza iziphumo zoxinzelelo lwe-alkali kunye neqondo lobushushu le-hydrothermal ukuya kwindawo yokugqibelaI-CEO2Ungeniso lwe-NAOSTORY MORGENCOM. Iziphumo zibonisa ukuba umsebenzi obalulekileyo unxulumene ngokuthe ngqo ne-CE3 + / CE4 + i-CE4 + i-oxtiotions kunye ne-Oxeji ye-Oxygen. Wei et al. I-ptnthethed ezintathu ze-pt /I-CEO2I-Catalysts ene-morphologue eyahlukileyo ye-carriers (i-rod efana (I-CEO2-R), ityhubhu (I-CEO2-C), kunye ne-octahedral (I-CEO2-O), elungele ngokukodwa kwiqondo lokunyanzelisa iqondo le-catalytic ye-C2H4. Bian Et Al. ilungiselelwe uthotho lweI-CEO2 I-nanomastenalialsNgentonga eyenziwe yintonga, i-cubic, i-granter, kunye ne-octahedral morphology, yafumanisa ukuba i-Catalysts ilayishwe kwiI-CEO2 I-Nanopartics(5NI / NPS) ibonakalise imisebenzi ephezulu kakhulu yokuzinza kunye nozinzo olungcono kune-catalysds kunye nezinye iintlobo zeI-CEO2Inkxaso.
2.Catalytic ukonakaliswa kweengcongconi emanzini
I-cerium oxideivunywa njenge-ozone esebenzayo ye-ozone oxibeys yokususwa kweendawo ezichongiweyo ezikhethiweyo. Xiao et al. ifumanise ukuba i-pp ye-nanoparccurclecles inxibelelana ngokusondeleyo neI-CEO2Kumgangatho ophambili kwaye ufumana unxibelelwano oluqinileyo, ngaloo nto ukuphuculwa komsebenzi we-ozone kunye nokuvelisa iintlobo zohlobo ze-telugen esebenzayo, ezinegalelo kwi-oxidation. UZhang Lanhe nabanye balungisiweI-CEO2/ Al22istSts. I-oxides yentsimbi ebiweyo ibonelela ngendawo yokuphendula yokuphendula phakathi kwe-organic complets kunye ne-O3, kukhokelela ekusebenzeni okuphezulu kweI-CEO2/ Al22O3 kunye nonyuko kwiindawo ezisebenzayo kwinkathalo enkulu
Ke ngoko, izifundo ezininzi zibonise okoi-cerium oxideI-Catalysts ye-catalysts ayinakuphela kuphela ukungcoliseka kwe-orgaincrection engcolisekileyo kwicandelo lonyango lwe-ozone lwamanzi amdaka, kodwa ikwaneziphumo eziveliswayo kwi-ozone ye-ozone. Banethemba elibanzi lokusetyenziswa kwe-ozone nyango.
I-3, i-Cataiction ikhutshiwe kwiindawo ezisebenza zezinto eziphilayo
I-CEO2, njengeyona nto inqabileyo yomhlaba oxinayo oxide, ifundwe i-Catalysisis ye-Multiphase ngenxa yomthamo ophezulu wokugcina ioksijini.
I-Wang et al. I-Synthethed a i-CE MN Expressional Oxide ene-morphology ye-rorphology (CE / Mn Molar Rateo ye-3: 7) Sebenzisa indlela ye-hydrothermal. I-Mn Ion yacocwa kwiI-CEO2Isakhelo siya kuthatha indawo ye-Ce, ngaloo ndlela sandisa ukugxininiswa kwezithuba zeoksijini. Njengoko i-CE4 + ithathelwa indawo yi-MN I-IOR, uninzi lwezithuba zomsebenzi zeoksijini zisenziwa, eso sesizathu somsebenzi ophezulu. Du el. I-Synthethed MN CE OXADSTS SEATSTS SETALSS usebenzisa indlela entsha yokudibanisa i-Reox Partication kunye neendlela ze-hydrothermal. Bafumanisa ukuba umyinge we-manganese kunyei-ceriumidlale indima ebalulekileyo ekumiselweni kwesizathu kwaye ichaphazele kakhulu intsebenzo yayo kunye nomsebenzi wayo.I-ceriumeManganesei-cerium oxideIdlala indima ebalulekileyo kwi-adsorvo, kwaye i-manganese ibonisiwe ukuba idlale indima ebalulekileyo kwi-oxidon. Ulungelelwaniso phakathi kweManganese kunye ne-cerium iphucula inkqubo yokuphendula ye-catalytic.
I-4.Photolyst
Ilanga et al. Ilungiselelwe ngempumelelo i-PR FE-0 @ c Sebenzisa indlela ye-CORCIPE. Indlela ethile kukuba ubungakanani be-PR, Fe, kunye ne-C udlala indima ebalulekileyo kwimisebenzi yefotocatalytic. Ukwazisa ngenani elifanelekileyo le-PR, Fe, kunye ne-C kwiI-CEO2Inokuphucula kakhulu impumelelo yefotocalytic yesampulu, kuba inolwazi olungcono longcoliseko, ukufuduka ngakumbi kokukhanya okubonakalayo, inqanaba lokwenza amaqela ekhabhoni, kunye nezithuba ezingaphezulu kweoksijini. Umsebenzi ophuculweyo wefotoI-CEO2-Golo i-nanocomposms ilungiselelwe nguGanesian et al. Ingabangelwa yindawo ephuculweyo yendawo, ubukhulu benkcitho, i-bandgap ye-bandgap, kunye nePhowudi yeFotoresse. Liu et al. ifumanise ukuba i-CE / COLOO4 Catalyst yifoto esebenzayo kakhulu nexabiso lesicelo elinokubakho. I-Petrovic et al. ilungiselelweI-CEO2I-Catalysts isebenzisa indlela ye-elektroded ye-elektrovision eyaziwayo kwaye yaziguqula nge-themospic ye-themospic engafunekiyo i-corona i-corona. Zombini izinto eziguqulweyo zePlasma eziguqulweyo nezingenziwe ezingafakwanga zibonisa amandla ahle kakhulu kwi-plasma kunye neenkqubo zokuphelisa iifoto.
Ukuqukumbela
Eli nqaku lihlaziya impembelelo yeendlela ze-synthesis zei-cerium oxidekwisurephology morphology, indima ye-morphology kwipropathi engaphezulu kunye nomsebenzi obalulekileyo, kunye nefuthe elilinganayo kunye nesicelo phakathii-cerium oxidekunye ne-dopants kunye nabathwali. Nangona i-cierium ye-cierium ye-cieium ye-ciesium ifundwe ngokubanzi yaza yasetyenziswa kwicandelo leCatalysis, kwaye lenze inkqubela phambili ebonakalayo ekusombululeni iingxaki ezifana nonyango lwamanzi, ziseziingxaki ezininzi, ezifana nokucacai-cerium oxideI-Morphology kunye nendlela yokuLayisha i-Cerium exhasiweyo. Olunye uphando luyafuneka kwindlela ye-synthesis, ukwandisa isiphumo sohlangano phakathi kwezinto, kwaye ufunda indlela ebalaseleyo yemithwalo eyahlukeneyo.
