Following the Modified Hummers method we have tried to prepare GO from natural graphite flakes. But we found two Bragg peaks ~11 and ~26 in XRD. It seems some graphite has not undergone to oxidize (according to the previous report). We used 1:0.5 (case-1) and 1:1 (case-2) graphite and NaNO3 for the synthesis.
The XRD patterns of as-synthesized samples are included below, please find them.
Dear Dr. Kaushik Shandilya,
Thank you for your comment. I would like to inform you that GO stands for Graphite oxide. It is a common name (GO) used popularly in the field of graphene.@Kaushik Shandilya,
Dear Dayal Chandra Roy ,
this issue has been often popped up here on RG;
so just an example of a lot of references such as Fig. 1 of:
Article The systemic effect of PEG-nGO-induced oxidative stress in v...
also Fig. 3 of:
Article Graphene Oxide and Its Electrochemical Performance
But there is also an interesting pattern in Fig. 3 of:
Article New Route to Synthesize of Graphene Nano Sheets
showing graphene nanosheet having a broad peak around 25°.
The peak at 26 ° is, to my opinion, due to graphite 002, which has not been completely oxydised as you have already assumed above ...
You should take an XRD pattern of your starting graphite material to compare the widths of the 26° peaks.
Best regards
G.M.
