Carbon Dioxide (CO2) ndiyo chigadzirwa chekupisa fossil mafuta uye iyo yakajairika greenhouse gasi, iyo inogona kushandurwa kudzoserwa mune zvinobatsira nenzira inoshamisa. Imwe nzira yekuvimbisa yekushandura CO2 emissions muFuel FeedStOck chiitiko chinonzi Electrochemical kuderedzwa. Asi kuti ave kuita basa rekutengesa, maitiro anofanirwa kuvandudzwa kuti asarudze kana kubereka zvimwe zvaunoda kabhoni-pfuma. Zvino, sezvakataurwa muenhau wechirembozha, Lawrenal Berkeley National Laboratory
"Kunyangwe tichiziva kuti mhangura yakanakisa yekuita izvi, hazvibatsire chibereko chemugove wechigadzirwa Kuperetera kwakati. "Chikwata chedu chakawana kuti iwe unogona kushandisa nharaunda yemunharaunda yeCATALYST yekuita dzakasiyana-siyana manomano ekupa rudzi urwu rwekusarudza."
Muzvidzidzo zvakapfuura, vaongorori vakagadza chimiro chaicho kuti vape nzvimbo dzakanakisa dzemagetsi uye nemakemikari kugadzira carbon-pfuma zvigadzirwa zvine kukosha kwekutengeserana. Asi aya mamiriro anopesana nemamiriro ezvinhu anoitika mumamiriro ezvinhu mumasero emununha anowanzoita masero ekugadzirisa mvura.
Kuti uzive dhizaini inogona kushandiswa muFael Cell yemvura nharaunda, sechikamu cheSimba Inosimudzira chirongwa cheSeeptine yeSion Fion, chinobvumira zvimwe mamorekuru ,.Ini) kuti ipfuure. Kusabvisa mamwe ions. Nekuda kwezvivakwa zvavo zvinosarudzika zveMakemikari, vanonyanya kukodzera kuve nekukanganisa kwakasimba pane microdentement.
Chanyaon Kim, postdoctoral mutsvagiro muBell Group uye wekutanga munyori wepepa, akakurudzirwa kuunganidza pamusoro pemhangura dziva nemapepuru ane miviri yeionion, nafion uye inotsigira. Chikwata chinyarira kuti kuita izvi kunofanira kuchinja nharaunda pedyo neCatalyst-inosanganisira iyo PH uye neimwe nzira yekutungamira maitiro ekugadzira zvigadzirwa zveCarbon izvo zvinogona kushandurwa nyore nyore kuita makemikari anobatsira. Zvigadzirwa uye mafuta emafuta.
Vatsvagiri vakashandisa denderedzwa rakatetepa reumwe neumwe weionomer maviri eIonommers kuimba yemhangura inotsigirwa neyepamhepo yekugadzira firimu, iyo yavaigona kuisa padhuze neyekupedzisira electrochemical sero. Kana majekiseni carbon dioxide mubhatiri uye kushandisa voltage, ivo vakayera huwandu hwacho hwazvino kuyerera kuburikidza nebhatiri. Vakabva vayera gasi uye mvura yakaunganidzwa mune yepedyo reservoir panguva yekuita. Nezve kesi mbiri, dzakawana iyo kabhoni-yakapfuma zvigadzirwa zvakaverengerwa 80% yesimba inodyiwa neyekuita-yakakwirira kupfuura makumi matanhatu muzana mune isina mhosva.
"Sangweji iyi inobatanidza inopa yakanakisa yenyika mbiri: Yakakwirira Chigadzirwa Kusarudza uye Yakakwirira Basa," bhero rakati. Iyo yakapetwa kaviri haina kungoitira zvakanaka kabhoni-pfuma, asi zvakare inogadzira iyo yakasimba yazvino panguva imwe chete, inoratidza kuwedzera kwebasa.
Vaongorori vakagumisa kuti mhinduro yakavandudzwa yaive mhedzisiro yeiyo yepamusoro co2 yekuvhara yakaunganidzwa mukubatanidza zvakananga pamusoro pemhangura. Mukuwedzera, zvakashata zvakabhadharwa mamorekuru anounganidza mudunhu pakati pevaIonomers anogadzira akaderera acidity yemuno. Izvi zvinosanganiswa zvinokatyamadza kutengeserana kwekutengeserana-kubva zvinowanzoitika mukushaikwa kweIonomer mafirimu.
Kuti uwedzere kuenderera mberi nekubudirira kwekuita, vaongorori vakatendeukira kune imwe chete tekinoroji inotsanangurwa iyo isingadei firimu seimwe nzira yekuwedzera co2 uye pH: yakadhonzwa voltage. Nekunyorera volistage voltage kune kaviri-layer ionomer kuunganidza, vaongorori vakawana kuwedzera kwe250% kuCarbon-pfuma vachienzaniswa neisina kuvhiringidzika uye static voltage.
Kunyangwe vamwe vaongorori vakatarisa basa ravo pakuvandudzwa kwevatsva vanochera, kuwanikwa kweiyo catalyst haina kuenderana nemamiriro ekushanda. Kudzora nharaunda pane iyo Catalyst Poult Iyo Iyo Nzira itsva uye dzakasiyana.
"Hatina kuuya nechero chitsva chokutadza, asi takashandisa kunzwisisa kwechiitiko uye takashandisa ruzivo urwu kutitungamira mukufunga nharaunda yeiyo nzvimbo yetalyst," akadaro Adam weber, mainjiniya mukuru. Masayendisiti ari mumunda wesimba tekinoroji kuBerkeley Laboratories uye Co-Munyori wemapepa.
Chinhanho chinotevera ndechekuwedzera kugadzirwa kweakachekwa maneja. Iyo Berkeley Lab timiniminary yekuedza yaisanganisira zvidiki zvidiki zvemhando yepamusoro, izvo zvaive zvakareruka kupfuura zvinhu zvakakura-zvakakura zvinodikanwa zvekushandisa zvekutengeserana. "Hazvina kuoma kushandisa coating pamusoro pefaira. Kuwedzera yechipiri denderedzwa yekubatanidza inova yakaoma. Imwe mukana ndeyekusanganisa uye kuendesa iyo maviri majasi pamwe chete mune solvent, uye tariro yekuti ivo vanoparadzanisa kana solvent inoputika. Ko kana vakasadaro? Bell akagumisa kuti: "Isu tinongofanira kuve takapusa." Tarisa kuKim C, BUI JC, Luo X nevamwe. Yakasarudzika Contalyst Microenvongement yeElectro-kuderedzwa kweCo2 kune akawanda-kabhoni zvigadzirwa uchishandisa kaviri-layer ionomer ichivharira pamhangura pamhangura pamhangura pamhangura pamhangura.

Ichi chinyorwa chinodzidziswa kubva pane zvinotevera zvinhu. Ongorora: Izvo zvinyorwa zvinogona kunge zvakarongedzerwa kureba uye zvirimo. Kuti uwane rumwe ruzivo, ndapota taura neiyo yakataurwa sosi.
