Carbon nanomaterials Taw qhia

Tau ntev, tib neeg tsuas paub tias muaj peb cov pa roj carbon allotropes: pob zeb diamond, graphite thiab amorphous carbon.Txawm li cas los xij, nyob rau hauv peb lub xyoos dhau los, los ntawm xoom-dimensional fullerenes, ib-dimensional carbon nanotubes, mus rau ob-dimensional graphene tau nrhiav tsis tu ncua, tshiab carbon nanomaterials txuas ntxiv mus nyiam lub ntiaj teb no.Cov pa roj carbon nanomaterials tuaj yeem muab faib ua peb pawg raws li qib ntawm nanoscale txwv ntawm lawv qhov loj me: xoom-dimensional, ib-dimensional thiab ob-dimensional carbon nanomaterials.
0-dimensional nanomaterials xa mus rau cov ntaub ntawv uas nyob rau hauv nanometer scale nyob rau hauv peb-dimensional qhov chaw, xws li nano-particles, atomic pawg thiab quantum dots.Lawv feem ntau yog tsim los ntawm ib tug me me ntawm atoms thiab molecules.Muaj ntau yam khoom siv zero-dimensional carbon nano-khoom, xws li carbon dub, nano-pob zeb diamond, nano-fullerene C60, carbon-coated nano-hlau hais.

Sai li qhovC60tau tshawb pom, chemists pib tshawb nrhiav qhov ua tau ntawm lawv daim ntawv thov rau cov catalyst.Tam sim no, fullerenes thiab lawv cov derivatives nyob rau hauv lub teb ntawm catalytic cov ntaub ntawv feem ntau muaj xws li peb yam nram qab no:

(1) fullerenes ncaj qha raws li catalyst;

(2) fullerenes thiab lawv cov derivatives ua homogeneous catalyst;

(3) Kev thov ntawm Fullerenes thiab lawv cov Derivatives hauv Heterogeneous Catalysts.
Cov pa roj carbon-coated nano-hlau hais yog ib yam tshiab ntawm xoom-dimensional nano-carbon-metal composite.Vim muaj kev txwv ntawm cov pa roj carbon plhaub thiab cov nyhuv tiv thaiv, cov hlau hais tuaj yeem raug kaw hauv qhov chaw me me thiab cov hlau nanoparticles coated nyob rau hauv tuaj yeem ruaj khov nyob rau hauv kev cuam tshuam ntawm ib puag ncig sab nraud.Hom tshiab no ntawm xoom-dimensional carbon-hlau nanomaterials muaj cov khoom siv optoelectronic tshwj xeeb thiab muaj ntau yam kev siv hauv kev kho mob, cov ntaub ntawv sib nqus, cov ntaub ntawv tiv thaiv electromagnetic, cov ntaub ntawv lithium roj teeb electrode thiab cov ntaub ntawv catalytic.

Ib-dimensional carbon nanomaterials txhais tau hais tias cov electrons txav mus los tsuas yog ib qho kev taw qhia uas tsis yog nanoscale thiab cov lus tsa suab yog linear.Cov neeg sawv cev ntawm ib sab ntawm cov ntaub ntawv carbon yog carbon nanotubes, carbon nanofibers thiab lwm yam.Qhov sib txawv ntawm ob tuaj yeem ua raws li txoj kab uas hla ntawm cov khoom kom paub qhov txawv, kuj tuaj yeem ua raws li qib ntawm graphitization ntawm cov khoom siv los txhais.Raws li txoj kab uas hla ntawm cov khoom txhais tau hais tias: txoj kab uas hla D hauv qab 50nm, cov qauv hauv hollow feem ntau hu ua carbon nanotubes, thiab txoj kab uas hla ntawm 50-200nm, feem ntau yog los ntawm ntau txheej graphite ntawv curled, nrog tsis muaj cov qauv Hollow feem ntau hu ua carbon nanofibers.

Raws li cov degree ntawm graphitization ntawm cov khoom, lub ntsiab txhais hais txog lub graphitization yog zoo dua, lub orientation ntawm lubgraphitedaim ntawv taw qhia thaum uas tig mus rau lub raj axis yog hu ua carbon nanotubes, thaum lub degree ntawm graphitization yog tsawg los yog tsis muaj graphitization qauv, qhov kev npaj ntawm cov graphite los xij yog disorganized, cov khoom nrog hollow qauv nyob rau hauv nruab nrab thiab txawm lubmultiwalled carbon nanotubestag nrho yog muab faib ua carbon nanofibers.Tau kawg, qhov sib txawv ntawm carbon nanotubes thiab carbon nanofibers tsis pom tseeb hauv ntau cov ntaub ntawv.

Hauv peb lub tswv yim, tsis hais txog qib ntawm graphitization ntawm carbon nanomaterials, peb paub qhov txawv ntawm cov pa roj carbon nanotubes thiab carbon nanofibers raws li qhov muaj lossis tsis muaj cov qauv hollow.Ntawd yog, ib-dimensional carbon nanomaterials txhais cov qauv hollow yog carbon nanotubes uas tsis muaj cov qauv hollow los yog cov qauv hollow tsis pom tseeb ib-dimensional carbon nanomaterials carbon nanofibers.
Ob-dimensional carbon nanomaterials: Graphene yog ib tug neeg sawv cev ntawm ob-dimensional carbon nanomaterials.Ob-dimensional functional cov ntaub ntawv uas sawv cev los ntawm graphene tau kub heev nyob rau hauv xyoo tas los no.Cov khoom siv hnub qub no qhia cov khoom tshwj xeeb hauv kev siv tshuab, hluav taws xob, cua sov thiab hlau nplaum.Structureally, graphene yog lub hauv paus chav tsev uas ua rau lwm cov ntaub ntawv carbon: nws warps mus txog xoom-dimensional fullerenes, curls rau hauv ib-dimensional carbon nanotubes, thiab stacks rau hauv peb-dimensional graphite.
Hauv cov ntsiab lus, carbon nanomaterials yeej ib txwm yog lub ntsiab lus kub hauv nanoscience thiab kev tshawb fawb thev naus laus zis thiab tau ua tiav kev tshawb fawb tseem ceeb.Vim lawv cov qauv tshwj xeeb thiab cov khoom zoo ntawm lub cev thiab tshuaj lom neeg, cov pa roj carbon nanomaterials tau siv dav hauv lithium-ion roj teeb cov ntaub ntawv, cov khoom siv hluav taws xob, Catalyst cab kuj, tshuaj lom neeg thiab cov khoom siv hluav taws xob, cov khoom siv hydrogen thiab cov khoom siv supercapacitor thiab lwm yam kev txhawj xeeb.

Tuam Tshoj Hongwu Micro-Nano Technology Co., Ltd - lub forerunner ntawm industrialization ntawm nano-carbon cov ntaub ntawv, yog thawj domestic chaw tsim tshuaj paus ntawm nanotubes thiab lwm yam nano-carbon ntaub ntawv rau industrial ntau lawm thiab daim ntawv thov ntawm lub ntiaj teb no txoj kev zoo, zus tau tej cov nano- Cov ntaub ntawv carbon tau raug xa tawm mus rau thoob plaws lub ntiaj teb, cov lus teb tau zoo.Raws li lub teb chaws txoj kev loj hlob lub tswv yim thiab modular tswj, Hongwu Nano ua raws li kev lag luam-oriented, technology-tsav, kom tau raws li qhov tsim nyog xav tau ntawm cov neeg muas zaub raws li nws lub hom phiaj, thiab ua unremitting siv zog los txhim kho lub zog ntawm Tuam Tshoj txoj kev lag luam.
