Kinds regards all !
I need help,
I got my data for the XRD Pattern of my Graphene Nanoplatelets (XGSciences supplier).
My questions are the following, I really appreciate if someone out there can help me with some of these ...
1. I have searched a little and I have found, there is a very characteristic peak in Graphite (so called Graphitic Peak?) at 26.2 ° =2Theta ,,, is this correct ?, If so, I can observe it on my graph. But I also can see another very little intense peak at 2theta = 55° , what does this peak represent in the case of the Graphene Nanoplatelets ?
(I have the XRD pattern attached below)
2. Can I determine the spacing lenght (d) between planes from my diffraction pattern ?
3. And third , How I can determine the particle size of my nanoplatelets, using the Scherre formula (d = (K*lambda)/[Beta*Cos(Theta)] , what I don't know is what to put as the value of K in this case; the dimensionless Shape Factor
When I get to compute this size d,(nm). What will this number mean ? , the diameter of the np ? or the thickness of the np ? (np = Graphene nanoplatelets)
Thank you so much, I will appreciate any help !

dear Franklin ; you can return to read the previous result of XRD patterns of graphite, graphene oxide and graphene .Article Facile and safe graphene preparation on solution based platform
Dear Mahmood H. M. :
Thank you for the article , I already gave it a reading, but it doesnt have any of the answers to any of my questions,
Can you say or provide some of the information I am looking regarding to the questions I posted ?
An additional question I have is:
What would be the two diffracted set of planes corresponding to the two peaks I can observe in my XRD Pattern ... Meaning, what are the diffracted-reflected planes corresponding to the positions of 2Theta = 26.25° & 2Theta = 55 ° (the two peaks we can observe on my Graph.
What I understand from the letter you shared is that what I have is not Graphene but Graphite , Am I correct ?
Kind Regards ! :)
yes it could be, that mean you haven't completed oxidation process to convert graphite to graphene oxide, which you have to subject it (GO) to subsequent reduction to convert it to graphene. with regards.
Dear Mahmood :
Thank You sir !
One more question, Would you have more references specifically about the subject of our discussion ?
Regards !
