Karolo ea bohlokoa ea lithupa tsa graphite in electrolysis: katleho, botsitso le bohlokoa ba indasteri 

Metsong ea sejoale-joale ea motlakase, lithupa tsa graphite li sebetsa e le likarolo tsa bohlokoa, haholo-holo joalo ka li-electrolys tsamaisong ea motlakase ea laboratoring le ea indasteri. Electrolysis, e sebelisang motlakase hajoale ho khanna liphetoho tsa lik'hemik'hale tse sa lumellaneng, e itšetleha haholo ka ts'ebetso ea lisebelisoa tsa elektrode tse sebetsang. Har'a lisebelisoa tse sebelisoang tse fapaneng, lithupa tsa graphing li hlahile e le thepa ea bona e ikhethang ka lebaka la boitšoaro ba bona bo ikhethang, ho leka-lekana hoa lik'hemina, le tšebeliso e theko e mengata.

Melemo ea bohlokoa ea lithupa tsa graphiti in electrolysis

1.Xcececececececececetel e ntlafatsang

Sebopeho sa Grafie se ne se lebisa moaparo oa Hxagonal " Sena se nolofalletsa phallo e tsitsitseng ea setaele le e nang le thata ea elektrolyte, e ts'ehetsang ho falla ha li-ion tse tsoelang pele 'me ka hona e boloka karabelo e ntle ea Remox e sebetsang. Sebaka sena se etsa hore Graphite Electise e tšoanele likopo tse kang tlhahiso ea clorine, hydrogen ea ho iphetola ha hylorine, le tšepe ea ho iphetola.

2. Bofelo ba lik'hemik'hale ba nang le taolo e laoloang

Ha Grayite e le sebakeng sa linomoro tse ngata tsa elektrolysis, haholo-holo ho fokotsa kapa ho nyenyefatsa mocheso o phahameng ka har'a litheko tse phahameng ka tlung ea oksijene, e hlahisa likhase tsa Co₂. Ho hanyetsanang ho tlhaselo ea lik'hemik'hale ka acid, Alkalis le makhopho a qhibiliha, ho holisa bohloeki ba motlakase.

3.superior ea futhumatsang ea futhumatsang

Phetoho ea Graphite e haufi le 3652 ° C (tlasa khatello e matla ea motlakase ea letsoai Ho feta moo, mokhoa oa eona oa AISIStropic o fana ka mokhoa oa ho tšoarella, ho fokotsa ho ts'oaroa kapa ho sebetsana, ka ho 'na oa sebetsana le bophelo ba elektrode.

4.EerctionRection

Mekhoa e meng ea electrolys, ho na le tlhahiso e makatsang ea aluminium, lithupa tsa graphite li sebetsa e le li-ades tse jang butle-butle tse lokelang ho etsoa tšebetso, ho fumana sebaka sa ho ikhotsofatsa kamehla. Tšobotsi ena ke paramente ea ts'ebetso e amang ts'ebetso ea tlhokomelo le moruo.

5.cost-sebetsa le bofokoli

Litsela tsa tlhaho tsa Graphite le litša tse tlase li fana ka melemo ea bohlokoa holim'a li-elektrode tsa bohlokoa tsa tšepe tse kang platinamo kapa khauta. Sena se etsa hore mofuta oa graphite o theohile ka sekala-kholo - ho tloha liseleng tsa laboratori e le limela tse ngata tsa laboratori lijalo tse kang clon-alkali le metallurgy.

Likarolo tse sebetsang tsa lisele tsa elektronis

Ka tatellano e tloaelehileng ea elektroly, lithupa tsa graphite li sebeletsa e le:

1.Chodes (li-electrode tse mpe

2.2H⁺ + 2E⁻⁻

3.ODES (electmbers e ntle), moo oxidation e sebelisang bocha. Mohlala, ions ea hydroxide (Oh⁻) lahleheloa ke li-elektrone ho hlahisa khase ea oksijene:

4.4oh⁻ - 4e⁻ → 2h₂o

Lisebelisoa tsa tlhaho tsa lik'hemik'hale le tšebeliso ea motlakase e tiisa hore li-electroni tsa li-electroni tsa motlakase li tsamaisana le phetiso ea liliti, ka hona ho boloka boitšoaro le botshepehi ba qotsitsoeng.

Lipuisano tsa indasteri le merusu ea mmaraka

Li-electrosi tsa setšoantšo li tšoaea liphoso liphuthehong tse fapaneng, ho kenyelletsa:

1.CHLER-alkali indasteri:Electrolysis of sodium chloride chloride ea ho hlahisa chlorine, caustic soda, le hydrogen, ea itšetleha ka li-asodes tsa khatello ea maikutlo bakeng sa ho tšoarella le boits'oaro.

2.Uruminum monko:Ha holo-héroult e sebetsana le li-anode tse jeoang kharaphite ho Molten Nelling, moo thepa ea elektrode e sebetsang hantle.

Meloko ea 3hydrogen:Ha e batla ho holang ha hydrojene e tala ea hydrojene e tala ea li-hydrojene e tala, li-elemite tse hlakileng li sebelisoa hohle ka li-almanaline le pem electrolyzers.

4.Wastewater kalafo:Li-profine tsa li-electrode tsa motlakase tsa prophite e kholo bakeng sa monko o litšila ka lebaka la botsitso ba bona.

5.Eenegy polokelo:Lipapatso tse thehiloeng ho litšoantšo li kenya letsoho theknoloji ea betri e latelang le mahlaseli a mafura, ka lipatlisiso tse tsoelang pele hore li ntlafatse tšebetso.

Mekhoa e Meno e Hlalosang le Potso ea Bokamoso

Patlisiso e ntse e tsoela pele ho hlahloba phetoho ea graphite, ho senya le ho kopanya li-graphene kapa khang ea motlakase, le ho fokotsa ho hanyetsa nako ea motlakase, le ho fokotsa likhakanyo tsa motlakase, le ho fokotsa ho hanyetsa nako ea motlakase. E le tokollo ea lefats'e ea matla le matla a lik'hemik'hale e tala, li-elektrone tse khabisitsoeng e tla lula e le thepa ea bona ea nakoana ka lebaka la motsoako oa tsona o ke keng oa bapisoa.
