Why are temperatures between 95 and 100 degrees centigrade optimum for reduced graphene oxide synthesis by Hydrazine from Grephene oxide?

In most papers 95 to 100 degree centigrade is used to synthesize RGO. Why arent temperatures above 100 degree like 150,200,250 used to synthesize graphene?

Graphite gives a peak at 43°, OK, but the most intense one is at 26°. Do you have such peak or only one at 43°? Without a peak at 26°, corresponding to the 002, it should not be graphite.

Alain

Subanta Majumdar

No I have not got a peak at 26 degree.

Lawrence Margulies

Can you please show your data. It will be possible to give you a meaningful answer if we can actually see the diffraction pattern.

Can you plz explain the form of your sample ? is it a film or solid or powder?

My sample is in powder form.

is OK

then some thing wrong in the alignment of sample or machine.

If I am not wrong you have used Bruker XRD? If so plz. check your sample with a Philips XRD
