Carbon nanomaterials Selelekela

Ka nako e telele, batho ba tseba feela hore ho na le carbon allotropes tse tharo: daemane, graphite le carbon amorphous.Leha ho le joalo, lilemong tse mashome a mararo tse fetileng, ho tloha ho fullerenes ea zero-dimensional, carbon nanotubes ea lehlakoreng le le leng, ho ea ho graphene ea mahlakore a mabeli e ntse e sibolloa, carbon nanomaterials e ncha e ntse e tsoela pele ho hohela tlhokomelo ea lefatše.Li-nanomaterials tsa carbon li ka aroloa ka mekhahlelo e meraro ho latela tekanyo ea tšitiso ea nanoscale ho litekanyo tsa tsona tsa sebaka: zero-dimensional, one-dimensional le two-dimensional carbon nanomaterials.
0-dimensional nanomaterials e bua ka thepa e sekalaneng sa nanometer sebakeng sa mahlakore a mararo, joalo ka li-nano-particles, lihlopha tsa athomo le matheba a quantum.Hangata li entsoe ka palo e nyenyane ea liathomo le limolek'hule.Ho na le lisebelisoa tse ngata tsa zero-dimensional carbon nano-materials, tse kang carbon black, nano-diamond, nano-fullerene C60, likaroloana tsa carbon-coated nano-metal.

Hang ha hoC60e ile ea sibolloa, litsebi tsa k'hemistri li ile tsa qala ho hlahloba monyetla oa kopo ea tsona ho catalyst.Hajoale, li-fullerenes le li-derivatives tsa tsona lefapheng la lisebelisoa tsa catalytic li kenyelletsa lintlha tse tharo tse latelang:

(1) fullerenes ka ho toba e le catalyst;

(2) fullerenes le derivatives bona e le homogeneous catalyst;

(3) Tšebeliso ea Fullerenes le Derivatives ea bona ho Heterogeneous Catalysts.
Likaroloana tsa nano-metal tse koahetsoeng ka carbon ke mofuta o mocha oa motsoako oa nano-carbon-metal oa zero-dimensional.Ka lebaka la ho fokotseha ha carbon shell le phello e sireletsang, likaroloana tsa tšepe li ka koalloa sebakeng se senyenyane 'me li-nanoparticles tsa tšepe tse koahetsoeng ka har'a tsona li ka ba teng ka mokhoa o tsitsitseng tlas'a tšusumetso ea tikoloho e ka ntle.Mofuta ona o mocha oa zero-dimensional carbon-metal nanomaterials o na le lisebelisoa tse ikhethang tsa optoelectronic 'me o na le mefuta e mengata haholo ea lisebelisoa tsa bongaka, lisebelisoa tsa ho rekota tsa makenete, lisebelisoa tsa tšireletso ea motlakase, lisebelisoa tsa lithium battery electrode le lisebelisoa tsa catalytic.

Li-nanomaterials tsa carbon-dimensional li bolela hore li-electrone li tsamaea ka bolokolohi ka tsela e le 'ngoe feela eo e seng ea nanoscale' me motsamao oa mela.Baemeli ba tloaelehileng ba lisebelisoa tsa carbon tse nang le lehlakore le le leng ke carbon nanotubes, carbon nanofibers le tse ling tse joalo.Phapang pakeng tsa tse peli e ka thehoa bophara ba lintho tse bonahalang ho khetholla, e ka boela ea e thehiloeng tekanyo ea graphitization ea lintho tse bonahalang tse ho hlalosoa.Ho ea ka bophara ba thepa e bolela hore: bophara ba D ka tlase ho 50nm, mohaho o ka hare oa sekoti o atisa ho bitsoa carbon nanotubes, 'me bophara ba bophara ba 50-200nm, haholo-holo ke letlapa la graphite le nang le mefuta e mengata. ha ho na meaho e hlakileng ea Hollow e atisang ho bitsoa carbon nanofibers.

Ho ea ka tekanyo ea graphitization ea thepa, tlhaloso e bua ka graphitization e molemo, mokhoa oagraphitesheet oriented parallel to the tube axis e bitsoa carbon nanotubes, ha tekanyo ea graphitization e le tlase kapa ha e na sebopeho sa graphitization, Tokiso ea maqephe a graphite ha e hlophisehe, thepa e nang le sebopeho se sekoti bohareng esita leli-nanotube tsa carbon tse nang le marako a mangatakaofela li arotsoe ka carbon nanofibers.Ha e le hantle, phapang pakeng tsa carbon nanotubes le carbon nanofibers ha e totobetse litokomaneng tse sa tšoaneng.

Ho ea ka maikutlo a rona, ho sa tsotellehe tekanyo ea graphitization ea carbon nanomaterials, re khetholla pakeng tsa carbon nanotubes le carbon nanofibers ho latela boteng kapa ho se be teng ha mohaho o se nang letho.Ka mantsoe a mang, li-nanomaterials tsa khabone tse nang le lehlakore le le leng tse hlalosang sebopeho se sekoti ke li-nanotube tsa carbon tse se nang sebopeho se sekoti Kapa sebopeho se sekoti ha se totobatse hore na carbon nanofibers ea lehlakoreng le le leng le le leng.
Li-nanomaterials tsa carbon-dimensional tse peli: Graphene ke moemeli oa li-nanomaterials tsa carbon-dimensional tse peli.Lisebelisoa tse sebetsang ka mahlakoreng a mabeli tse emeloang ke graphene li chesitse haholo lilemong tsa morao tjena.Lintho tsena tsa linaleli li bonts'a thepa e ikhethang e makatsang ho mechini, motlakase, mocheso le makenete.Ka sebopeho, graphene ke yuniti ea mantlha e etsang lisebelisoa tse ling tsa khabone: e pota-pota ho fihlela ho zero-dimensional fullerenes, e-curls ho ba li-nanotube tsa khabone e le 'ngoe,' me e bokellana ho graphite ea mahlakore a mararo.
Ka bokhutšoanyane, carbon nanomaterials esale e le taba e chesang haholo lipatlisisong tsa nanoscience le thekenoloji 'me e entse tsoelo-pele ea bohlokoa ea lipatlisiso.Ka lebaka la sebopeho sa bona se ikhethang le thepa e ntle ea 'mele le ea lik'hemik'hale, carbon nanomaterials e sebelisoa haholo ka lisebelisoa tsa betri tsa lithium-ion, lisebelisoa tsa optoelectronic , Catalyst carriers, lik'hemik'hale tsa lik'hemik'hale le tsa likokoana-hloko, lisebelisoa tsa polokelo ea hydrogen le lisebelisoa tsa supercapacitor le likarolo tse ling tse amehang.
