According to some papers, graphene is oxidised to GO and reduced to rGO. Instead of doing so, why don't just directly use pristine graphene? Explanation on this or will be highly appreciated. Suggestions on reference papers is also appreciated.
Hi Tan,
With reduction of GO to rGO one is able to tune the degree of electronic and protonic conductivity of the sample depending on the degree of reduction.
Best,

Your question title mentions "graphite" but your elaboration uses "graphene." I assume your title is accurate because it makes no sense if you already have graphene but need to make rGO (a type of slightly oxidized graphene).
Oxidizing graphite to graphene oxide is a necessary step to exfoliate graphite and obtain graphite layers (though highly oxidized). To restore the sp2-network, a reduction process is followed to remove the oxygen functional groups on GO and result in rGO.
Arman Bonakdarpour Tianyu Liu I see, thank you for the clarifications.
