I have performed XRD analysis and other than the normal peaks at 13 and 27 I have two other peaks at 38 and 44 which I am unable to find in the literature.
Hello Adeem Ghaffar Rana I see peaks in that region (Copper Radiation!) for some other Carbon Nitride phase CN2 (01-082-3305). Maybe your sample isn't that pristine? Can you share the Scan, that would make it much easier to execute a full search/match?

Hello Adeem Ghaffar Rana Its strange that these peaks at higher angles both have totally different FWHM. Could it be that you are shining X-rays next to your sample or on the sample holder (what is it?) and get peaks from there? It would be good to measure to a higher angle, like 120 degrees, to confirm/exclude possible phases in the PhaseID.
There is actually a card of C3N4 that matches these two narrow peaks, this phase would show 2 more peaks between 60 and 70 degrees.
Thomas Degen If I am getting these peaks is it strange or what it represents because in literature it's not be shown if someone has shown these haven't explained anything about it.
Hello Adeem Ghaffar Rana we don't know yet what is going on. If these peaks are from an impurity or from the sample support. You can't solve a Multi Phase ID with just 4 peaks. Please make a Scan to much larger 2Theta (120/150 deg) to see more reflections. That's the way to uniquely rule out or identify Phases. What's your measurement setup, sample holder etc?
If I am correct that you are asking about graphitic C3N4, then what you are looking at is at least a 2-phase mixture - the graphitic material is characterized by the very broad peaks, and the very sharp peaks are from a 2nd phase with composition probably exactly as described by Thomas Degen already.
What's your base precursor? Did you close with aluminum foil directly?
