Muaj ntau ntau yam oxidants, feem ntau siv oxidants yog cov potassium permanganate, potassium trioxide, xws li hydrogen peroxide, nitric acid, thiab lwm yam). Nws nyob hauv xyoo tas los uas Potassium permanganate yog lub ntsiab oxidant siv hauv kev npaj graphite.
Nyob rau hauv qhov kev txiav txim ntawm oxidizer, graphite yog oxidized thiab nruab nrab network macromolecules nyob rau hauv graphite txheej ua planar pacromolecules nrog tus nqi them zoo. Vim yog cov nyhuv uas tsis muaj txiaj ntsig ntawm tib tus nqi zoo, qhov kev ncua deb ntawm cov txheej txheem graphite nce, uas muab cov channel thiab chaw rau cov txheej txheem kom nkag mus rau txheej graphite. Hauv cov txheej txheem npaj ntawm kev nthuav dav graphite, tus neeg sawv cev sib npaug yog cov kua qaub. Nyob rau hauv xyoo tas los no, cov kws tshawb nrhiav tsuas yog siv cov sulfuric acid, nitric acid, nitric acid, perchloric acid, perchloric acid, sib xyaw kua qaub thiab glacial acetic acid.
Cov qauv hauv tshuab hluav taws xob yog nyob rau hauv ib qho kev tawm tsam tas li, cov khoom siv hlau, cov hlau tso rau hauv electrolyte raws li cathhode, sib haum lub voj kaw; Lossis graphite tshem tawm hauv electrolyte, hauv electrolyte nyob rau hauv tib lub sij hawm tso rau hauv qhov tsis zoo thiab zoo phaj yog energized txheej txheem, anodic oxidation. Qhov saum npoo ntawm graphite yog oxidized rau carbocation. Nyob rau tib lub sijhawm, nyob rau hauv cov kev ua ke ntawm electrostatic sib txawv, acid ions lossis lwm yam ntawm cov khaubncaws sab nraud povtseg los ua cov kab tsuag uas nthuav dav.
Piv nrog cov tshuaj oxidation oxidation, enctrochemical cov qauv yog qhov muaj kuab paug, tus nqi kev pabcuam ib puag ncig yog qhov tsawg, thiab lub neej tsis ntev los no, hluav taws xob tsis ntev los no, Electrochemical Txoj kev tau maj mam dhau los ua txoj kev nyiam ua rau npaj graphite uas muaj ntau yam kev lag luam nrog ntau cov txiaj ntsig.
Cov roj av-theem diffusion txoj kev yog los tsim cov kev sib txuas ntawm cov kab ke thiab cov kab ke thiab cov kab ke sib xyaw
Cov txiaj ntsig zoo: tus qauv thiab kev txiav txim ntawm cov tshuaj reactor tuaj yeem tswj tau, thiab cov reactants thiab cov khoom tuaj yeem sib cais tau yooj yim.
Qhov tsis zoo: Cov khoom siv tshuaj tiv thaiv yog qhov nyuaj, yog li cov tshuaj tiv thaiv ib puag ncig muaj zog, yog li cov tshuaj tiv thaiv ib puag ncig, yog li cov tshuaj tiv thaiv tau muaj siab, thiab tsis haum rau cov kev siv ntau lawm.
Cov qauv sib xyaw ua kua yog txhawm rau sib xyaw cov khoom siv nrog cov roj ntsha, raws li kev tiv thaiv roj lossis kev sib khi ua haujlwm rau npaj graphite. Nws yog feem ntau siv rau synthesis ntawm alkali hlau-graphite interlaminar compounds (gics).
Cov txiaj ntsig: Cov txheej txheem tshuaj tiv thaiv yooj yim, cov tshuaj tiv thaiv nrawm nrawm nrawm, los ntawm kev hloov graphite, ntau haum rau huab hwm coj ntau lawm.
Qhov tsis zoo: Cov khoom tsim tau tsis ruaj khov, nws yog qhov nyuaj rau kev cuam tshuam nrog cov khoom siv dawb uas txuas nrog cov graphite interlamellar tebchaw thaum coob tus synthesis.
Cov txheej txheem melting yog los sib xyaw graphite nrog cov khoom siv sib xyaw ntawm cov kab ke ntawm cov kab ke (hauv qab no los ntawm cov tshuaj txhuam hniav (hauv qab no)) Hlau Chlorides - Gics.
Cov txiaj ntsig: Cov khoom siv hluav taws xob muaj kev ruaj khov, yooj yim ntxuav, ntsuas kub yooj yim, haum rau kev tsim khoom loj.
