Vatsvagiri veGerman vakashuma mune yazvino chinyorwa cheUK magazini Nature kuti vakagadzira nzira nyowani yekunyungudutsa iyo inogona kushandura yakasimba simbi oxides kuita block-shaped alloys mune imwe nhanho. Iyo tekinoroji haidi kunyungudutswa nekusanganisa simbi mushure mekunge yaburitswa, izvo zvinobatsira kuderedza kuburitsa gasi rinopisa uye kuchengetedza simba.

Vatsvakurudzi veMax Planck Institute for Sustainable Materials muGermany vakashandisa hydrogen panzvimbo yekabhoni sechinhu chinoderedza kuburitsa simbi uye kugadzira alloy patembiricha iri pasi penzvimbo yekunyunguduka kwesimbi, uye vakabudirira kugadzira alloys akaderera-yekuwedzera mukuyedza. Iyo yakaderera-yekuwedzera alloys inoumbwa ne64% iron uye 36% nickel, uye inogona kuchengetedza vhoriyamu yavo mukati mehombe tembiricha renji, ichiita kuti ishandiswe zvakanyanya muindasitiri.

Vatsvakurudzi vakavhenganisa maokisi esimbi uye nickel muchikamu chinodiwa kune alloys akaderera-anowedzera, vakaakuya zvakaenzanirana neguyo rebhora ndokuadzvanya kuita makeke madiki akatenderera. Vakabva vapisa makeke muchoto kusvika ku700 degrees Celsius uye vakaunza hydrogen. Tembiricha yakanga isina kukwirisa zvekunyungudusa iron kana nickel, asi yaive yakakwira zvekudzikisa simbi. Miedzo yakaratidza kuti iyo yakagadziridzwa simbi yakaita simbi yaive neyakajairwa maitiro eiyo yakaderera-yekuwedzera alloys uye yaive nani michina michina nekuda kwehukuru hwayo hwezviyo. Nekuti chigadzirwa chakapedzwa chaive muchimiro chebhuroko kwete poda kana nanoparticles, zvaive nyore kukanda nekugadzirisa.

Traditional alloy kunyunguduka kunosanganisira matanho matatu: kutanga, simbi oxides muore inoderedzwa kuita simbi nekabhoni, ipapo simbi inobviswa decarbonized uye simbi dzakasiyana dzinonyungudutswa nekusanganiswa, uye pakupedzisira, thermal-mechanical processing inoitwa kugadzirisa microstructure ye. iyo alloy kuti ipe chaiyo zvimiro. Matanho aya anodya simba rakawanda, uye maitiro ekushandisa kabhoni kuderedza simbi anoburitsa huwandu hwakakura hwecarbon dioxide. Kabhoni inobuda muindasitiri yesimbi inosvika gumi kubva muzana yepasi rose.

Vatsvagiri vakati iyo byproduct yekushandisa hydrogen kuderedza simbi imvura, ine zero kabhoni emissions, uye kuti iri nyore maitiro ane mukana wakakura wekuchengetedza simba. Nekudaro, zviedzo zvakashandisa maokisi esimbi uye nickel yekuchena kwepamusoro, uye kugona
