Ikoranabuhanga rishya rizamura ihinduka rya Dioxyde ya Carbone mumavuta

Uzuza urupapuro rukurikira kandi tuzaguhamagara verisiyo ya PDF ya "Iterambere ryikoranabuhanga rishya kugirango uhindure dioxyde de carbone mumashanyarazi"
Dioxyde de Carbone (CO2) nigicuruzwa cyaka ibiti byaka kandi gaze ya parike isanzwe, ishobora guhinduka mubice byingirakamaro muburyo burambye. Inzira imwe isezeranya guhindura imyuka yimkanda yimkane mumashyamba ya lisansi nuburyo bwitwa igabanuka rya electrochemical. Ariko kugirango uhangane mubucuruzi, inzira ikeneye kunozwa kugirango ihitemo cyangwa kubyara ibicuruzwa byinshi byifuzwa. Noneho, nkuko byatangajwe mu ingufu za kamere, Laboratwari ya Laboratwari yigihugu (Berkeley Laboratoire) yateguye uburyo bushya bwo kuzamura ubuso bw'umuringa bukoreshwa mubyifuzo byafasha, bityo bikongera guhitamo inzira.
Umuhanga mukuru muri Berkeley witwa Berkeley yagize ati: "Nubwo ari umwarimu ufite umusembuzi mwiza muri kaminuza ya Californiya, Berkeley. Umurozi. Ati: "Ikipe yacu yasanze ushobora gukoresha ibidukikije bya catalyst gukora amayeri atandukanye yo guhitamo."
Mu masomo ya mbere, abashakashatsi bashyizeho uburyo bunoze bwo gutanga amashanyarazi meza n'imiti yo gukora ibicuruzwa bikungahaye bya karubone hamwe n'agaciro k'ubucuruzi. Ariko ibi bintu binyuranye nibihe bisanzwe bibaho muburyo busanzwe bwa lisansi ukoresheje ibikoresho bishingiye kumazi.
Mu rwego rwo kumenya igishushanyo gishobora gukoreshwa mu mazi y'amazi ya lisansi, mu rwego rw'umushinga wo guhanga udushya mu mirimo ya Mininomer, rituma molekile zishyuwe (ion) kunyuramo. Ukuyemo izindi nyoni. Bitewe nibintu byabo bya shimi cyane, birakwiriye cyane cyane kubera kugira ingaruka zikomeye kuri microengoilment.
Chanyoon Kim, umushakashatsi wa posita mu itsinda ndetse n'umwanditsi wa mbere w'impapuro, yasabye ko yambaye ubuso bw'umuringa hamwe na iOnomers ebyiri, Nafion n'ibikorwa. Itsinda ryashakaga ko kubikora bigomba guhindura ibidukikije hafi ya catalyst - harimo na PH n'amazi ya karuboni - muburyo bumwe bwo kuyobora reaction kubyara umusaruro wa karubone. Ibicuruzwa n'amazi.
Abashakashatsi bakoresheje urwego ruto rwa buri gionomer hamwe nigice kabiri cya ionomers ebyiri kuri firime yumuringa zishyigikiwe na firime, zishobora kwinjiza hafi yimpera ya selile ifite imiti yintoki. Iyo inshinge za karubone muri bateri kandi zishyira mu bikorwa voltage, zapimye iki gihe cyaturutse kuri bateri. Hanyuma bapima gaze n'amazi yakusanyirijwe mu kigega cyegeranye mugihe cy'igisubizo. Ku rubanza rw'ibirimo, basanze ibicuruzwa bikungahaye bya karubone bibaye 80% by'ingufu zikoreshwa na reaction-kurenza 60% mu rubanza rwanduye.
Bell ati: "Iyi ngoro ya sandwich itanga ibyiza by'isi byombi: Guhitamo ibicuruzwa byinshi no gukora cyane." Ubuso bubiri-ntabwo ari bwiza kubicuruzwa bikize bya karubone, ahubwo bitanga ikiriho gikomeye icyarimwe, byerekana ko ibikorwa.
Abashakashatsi banzuye ko igisubizo cyateye imbere ari ibisubizo bya Conntration yo hejuru yibanda ku icumbi hejuru y'umuringa. Mubyongeyeho, molekile zishinjwaga cyane mukarere hagati ya ionomers zombi zizatanga aside iri hasi. Uku guhuza ibicuruzwa byo kwibandaho bikunda kubaho mugihe udahari films.
Kugira ngo babone uburyo bwo kurushaho kunoza imikorere, abashakashatsi bahinduye ikoranabuhanga ryagaragaye mbere bidasaba firime ya iOnomer nk'ubundi buryo bwo kongera CO2 na PH: Voldage. Mugukoresha voltage yakuweho ku buhinzi bubiri bwa Ionomer.
Nubwo bamwe mu bashakashatsi begeranya imirimo yabo ku iterambere ry'amasetano mashya, kuvumbura umusemburo ntizirikana ibisabwa. Kugenzura ibidukikije hejuru yubusambanyi nubu buryo bushya kandi butandukanye.
Adam Heber, Adamu Weber yagize ati: "Ntabwo twazanye umusembuzi mushya rwose, ariko twifashishije imyumvire yacu ya kinetike kandi dukoresha ubu bumenyi kugira ngo tuyayobore mu gutekereza ku bidukikije urubuga rwa catalyst." Abahanga mu rwego rw'ikoranabuhanga ry'ingufu kuri Laboratoire ya Berkeley no gufatanya impapuro.
Intambwe ikurikira ni ugugura umusaruro wa katalire yambaye. Ubushakashatsi bwakozwe na Berkeley Lab burimo sisitemu ntoya yicyitegererezo, byari byoroshye cyane kuruta imiterere nini-ubuso bukoreshwa kubisabwa mubucuruzi. Bell ati: "Ntabwo bigoye gukoresha ipfundo ku buso. Ariko uburyo bw'ubucuruzi bushobora kuba bukubiyemo guhana imipira ntoya z'umuringa," inzoka. Ongeraho igice cya kabiri cyo gupfumba gihinduka ingorabahizi. Ikintu kimwe nukuvanga no kubitsa amakoranire abiri hamwe muburyo bworoshye, kandi wizere ko batandukanye mugihe igisubizo cyuzuye. Byagenda bite se niba batabikora? Bell yashojwe agira ati: "Tugomba kugira ubwenge gusa." Reba kuri Kim C, Bui JC, Luo X nabandi.

Iyi ngingo ikomoka mubikoresho bikurikira. Icyitonderwa: Ibikoresho bishobora kuba byarahinduwe muburebure nibirimo. Kubindi bisobanuro, nyamuneka hamagara isoko yavuzwe.
