Usoro kemịkalụ na-ebu ụzọ oxidize graphite n'ime graphite oxide site na mmeghachi omume oxidation, ma na-abawanye ohere oyi akwa site na iwebata ikuku oxygen nwere otu ọrụ na atom carbon n'etiti ọkwa graphite, si otú ahụ na-ebelata mmekọrịta dị n'etiti n'ígwé.

Ọksidation nkịtị

Ụzọ ndị a gụnyere usoro Brodie, usoro Staudenmaier na usoro Hummers [40].Ụkpụrụ bụ ịgwọ graphite na acid siri ike nke mbụ,

Mgbe ahụ tinye oxidant siri ike maka oxidation.

A na-ewepụ graphite oxidized site na ultrasonic iji mepụta graphene oxide, wee belata site na ịgbakwunye onye na-ebelata ego iji nweta graphene.

Ndị na-ebelata ihe ndị na-emekarị gụnyere hydrazine hydrate, NaBH4 na mbelata alkali ultrasonic siri ike.NaBH4 dị ọnụ ma dị mfe idowe element B,

Ọ bụ ezie na mbelata alkali ultrasonic siri ike dị mfe na enyi na gburugburu ebe obibi, ọ na-esiri ike ibelata *, na ọnụ ọgụgụ dị ukwuu nke ọrụ ọrụ oxygenated ga-anọgide na-adị mgbe mbelata,

Ya mere, a na-ejikarị hydrazine hydrate dị ọnụ ala karịa iji belata graphite oxide.Uru nke mbelata hydrazine hydrate bụ na hydrazine hydrate nwere ikike mbelata siri ike ma dị mfe ịmegharị, yabụ na ọ gaghị enwe ihe adịghị ọcha fọdụrụ na ngwaahịa ahụ.N'ime usoro mbelata, a na-agbakwunye mmiri amonia kwesịrị ekwesị iji meziwanye ikike mbelata nke hydrazine hydrate,

N'aka nke ọzọ, ọ nwere ike ime ka elu nke graphene na-atụgharị ibe ya n'ihi ebubo na-adịghị mma, si otú ahụ belata agglomeration nke graphene.

Enwere ike ime nkwadebe dị ukwuu nke graphene site na usoro oxidation na usoro mbelata, yana ngwaahịa graphene oxide nke etiti nwere ezigbo mgbasa na mmiri,

Ọ dị mfe ịgbanwe ma rụọ ọrụ graphene, ya mere a na-ejikarị usoro a eme ihe na nyocha nke ihe ndị mejupụtara na nchekwa ike.Ma n'ihi na oxidation
