Abacwaningi baseJalimane baye babika kumagazini wakamuva wephephabhuku lase-UK i-Nature ukuthi baye bahlakulela inqubo entsha yokuncibilikisa i-alloy engakwazi ukuguqula ama-oxide ensimbi aqinile abe ama-alloys anjenge-block ngesinyathelo esisodwa. Ubuchwepheshe abudingi ukuncibilika nokuxuba insimbi ngemva kokuba isikhishiwe, okusiza ukunciphisa ukukhishwa kwamagesi abamba ukushisa nokonga amandla.

Abacwaningi e-Max Planck Institute for Sustainable Materials eJalimane basebenzisa i-hydrogen esikhundleni sekhabhoni njenge-ejenti yokunciphisa ukuze kukhishwe insimbi futhi benze ingxubevange emazingeni okushisa angaphansi kakhulu kwendawo yokuncibilika kwensimbi, futhi baye bakhiqiza ngempumelelo ama-alloys anwebeka kancane ekuhlolweni. Ama-alloys anwebeka kancane akhiwe ngensimbi engu-64% kanye ne-nickel engu-36%, futhi angagcina umthamo wawo ngaphakathi kwebanga lokushisa elikhulu, okwenza asetshenziswe kabanzi embonini.

Abacwaningi baxuba ama-oxide ensimbi ne-nickel esilinganisweni esidingekayo sama-alloys anwebeka kancane, bawagaya ngokulinganayo ngogayo lwebhola bese bewacindezela aba amakhekhe ayindilinga amancane. Babe sebeshisisa amaqebelengwane esithandweni aze afike ku-700 degrees Celsius base bethula i-hydrogen. Izinga lokushisa lalingekho phezulu ngokwanele ukuncibilikisa insimbi noma i-nickel, kodwa laliphezulu ngokwanele ukunciphisa insimbi. Ukuhlola kubonise ukuthi insimbi ecutshunguliwe emise okwebhulokhi yayinezici ezijwayelekile zama-alloys anwebeka kancane futhi yayinezakhiwo ezingcono zokukhanda ngenxa yosayizi wayo wokusanhlamvu omncane. Ngenxa yokuthi umkhiqizo oqediwe wawusesimweni se-block esikhundleni se-powder noma i-nanoparticles, kwakulula ukuphonsa nokucubungula.

Ukuncibilikiswa kwe-alloy yendabuko kuhilela izinyathelo ezintathu: okokuqala, ama-oxide ensimbi ku-ore ancishiswa abe yinsimbi nge-carbon, bese insimbi ikhishwa futhi izinsimbi ezihlukene ziyancibilika futhi zixutshwe, futhi ekugcineni, ukucutshungulwa kwe-thermal-mechanical kwenziwa ukuze kulungiswe i-microstructure. ingxubevange ukuyinikeza izakhiwo ezithile. Lezi zinyathelo zisebenzisa amandla amakhulu, futhi inqubo yokusebenzisa ikhabhoni ukunciphisa izinsimbi ikhiqiza inani elikhulu le-carbon dioxide. Ukukhishwa kwekhabhoni okuvela embonini yensimbi kufinyelela cishe ku-10% wengqikithi yomhlaba.

Abacwaningi bathi i-byproduct yokusebenzisa i-hydrogen ukunciphisa izinsimbi ngamanzi, angenayo i-carbon emissions, nokuthi inqubo elula inamandla amakhulu okonga amandla. Kodwa-ke, ucwaningo lwasebenzisa ama-oxide ensimbi ne-nickel yokuhlanzeka okuphezulu, nokusebenza kahle
