Txoj kev txhim kho ntawm kev huv thiab lub zog txuas ntxiv yog lub tswv yim loj rau peb lub teb chaws txoj kev loj hlob thiab kev lag luam. Hauv txhua theem ntawm cov tshuab hluav taws xob tshiab, hluav taws xob cia muaj txoj haujlwm tseem ceeb heev, thiab nws kuj yog qhov kev tshawb fawb kub hauv kev tshawb fawb tam sim no. Raws li hom tshiab ntawm ob-seem qauv qauv ua qauv, daim ntawv thov ntawm graphene muaj qhov tseem ceeb thiab muaj peev xwm loj hlob hauv daim teb no.

Graphene tseem yog ib qho kev txhawj xeeb tshiab tshaj plaws tshiab. Nws cov qauv yog tsim ntawm ob qho kev sib dhos, cov kev ua zes. Doping nrog heterogeneous atoms yog ib txoj kev tseem ceeb kom tawg cov qauv qauv thiab hloov nws lub cev cov zog. Nitrogen atoms muaj qhov loj me uas nyob ze rau ntawm cov pa roj carbon atoms thiab yog qhov yooj yim kom tau doped rau hauv kev sib dhos ntawm graphene. Yog li ntawd, nitrogen doping ua lub luag haujlwm tseem ceeb hauv kev tshawb fawb ntawm cov ntaub ntawv graphene. Hloov chaw nrog doping tuaj yeem siv los hloov cov khoom hluav taws xob hauv graphene thaum lub sijhawm kev loj hlob.

Graphene doped nitrogentuaj yeem qhib lub zog band sib txawv thiab kho cov qauv siv hluav taws xob, thiab cov cab kuj nce hluav taws xob ceev, yog li kev txhim kho qhov kev coj zoo thiab kev ruaj ntseg ntawm graphene. Ib qho ntxiv, kev qhia ntawm nitrogen-muaj cov qauv atomic rau hauv cov pa carbon daim phiaj adsorbed ntawm graphene nto, yog li txhawb kev sib cuam tshuam ntawm cov hlau me me thiab graphene. Yog li, daim ntawv thov ntawm nitrogen-doped graphene rau lub zog cia khoom siv tau ntau dua superform electrofode khoom. Cov kev tshawb fawb uas twb muaj lawm kuj qhia tau tias nitrogen-doped graphene tuaj yeem txhim kho cov yam ntxwv hluav taws xob, thiab muaj peev xwm hloov chaw nyob sai thiab hloov chaw loj loj hauv teb ntawm kev cia khoom.

Nitrogen-doped graphene

Nitrogen-doped graphene yog ib txoj hauv kev tseem ceeb kom paub txog kev ua haujlwm ntawm graphene, thiab nws plays lub luag haujlwm tseem ceeb hauv kev nthuav dav cov ntawv thov. N-doped graphene tuaj yeem txhim kho cov yam ntxwv hluav taws xob, thiab lub neej hloov hluav taws xob, thiab lub sijhawm tshem tawm cov hluav taws xob, lithium roj roj teeb lithium.
