I prepared a graphene oxide-coated granular activated carbon composite for my research. I characterized the composite using SEM and found graphene sheets on the GAC surface. However, while doing the XRD analysis, I did not get any graphene oxide peak on the XRD pattern of the composite. All the peaks I found are relevant to activated carbon. See the attached images. Could anyone please explain this phenomenon?
Dear Tanvir Ahamed
Looking at your spectrum I can see:
Peak intensity is less than 4500 cts.
Please increase your measurement time. I think at least 10 times or even more. Because the intensity of the GO peak is often very weak and can be mixed into the background.
Dear Tanvir Ahamed , have you tried to take XRD from 2theta=5 degree?
Because the XRD peak for GO could also be positioned around 2theta=9-10 degree, depending on certain factors such as exfoliation of GO layers.
Dear Gayathri Unnikrishnan
Thank you for your response. Actually, data presented on the figure was taken from 2theta = 5-80.
