Hydrogen tau nyiam ntau yam vim nws cov peev txheej ntau, txuas ntxiv dua tshiab, ua haujlwm siab thermal, tsis muaj kuab lom thiab tsis muaj pa roj carbon emissions.Tus yuam sij rau kev txhawb nqa ntawm hydrogen zog yog nyob rau hauv yuav ua li cas khaws hydrogen.
Ntawm no peb sau qee cov ntaub ntawv ntawm nano hydrogen cia khoom raws li hauv qab no:
1.Qhov thawj zaug pom hlau palladium, 1 ntim ntawm palladium tuaj yeem yaj ntau pua lub ntim ntawm hydrogen, tab sis palladium yog kim, tsis muaj txiaj ntsig.
2.Qhov ntau ntawm hydrogen cia cov ntaub ntawv yog nce zuj zus mus rau alloys ntawm kev hloov hlau.Piv txwv li, bismuth nickel intermetallic compounds muaj cov khoom ntawm reversible absorption thiab tso tawm ntawm hydrogen:
Txhua gram ntawm bismuth nickel alloy tuaj yeem khaws 0.157 litres ntawm hydrogen, uas tuaj yeem rov tso tawm los ntawm cua sov me ntsis.LaNi5 yog nickel-based alloy.Cov hlau-raws li hlau tuaj yeem siv los ua cov khoom siv hydrogen nrog TiFe, thiab tuaj yeem nqus thiab khaws 0.18 litres ntawm hydrogen ib gram ntawm TiFe.Lwm yam magnesium-based alloys, xws li Mg2Cu, Mg2Ni, thiab lwm yam, kuj pheej yig.
3.Cov pa roj carbon nanotubesmuaj cov thermal conductivity zoo, thermal stability thiab zoo heev hydrogen absorption zog.Lawv yog cov additives zoo rau Mg-based hydrogen cia cov ntaub ntawv.
Ib leeg-walled carbon nanotubes (SWCNTS)muaj kev cog lus thov hauv kev tsim cov khoom siv hydrogen cia raws li cov tswv yim tshiab lub zog.Cov txiaj ntsig tau pom tias qhov siab tshaj plaws hydrogenation degree ntawm carbon nanotubes nyob ntawm txoj kab uas hla ntawm carbon nanotubes.
Rau ib leeg-walled carbon nanotube-hydrogen complex nrog ib txoj kab uas hla ntawm 2 nm, hydrogenation degree ntawm carbon nanotube-hydrogen composite yog yuav luag 100% thiab cov hydrogen cia muaj peev xwm los ntawm qhov hnyav yog ntau tshaj 7% los ntawm kev tsim ntawm reversible carbon- hydrogen bonds, thiab nws ruaj khov ntawm chav tsev kub.
