I have synthesized a ceramic-based nanomaterial by hydrothermal synthesis method. How I can confirm which chemical compound is formed. Should I go with the XRD analysis or any others?
it is always good to do a characterization by x ray diffraction, and eletronic microscopy. but you can add some chemical analisys to identify the presence of chemical elements like eds/ wds or x ray fluorescence, among others. I suggest you to see the papers you used in your research to identify the characterization techniques normally used for your material.
Agree with Silas, refer to the literature of your synthesized materials for guidance.
You may simply go with XRD and match it with reported XRD patterns. In case your compound is new, then your XRD data is needed to be analysed more deeply. Deep XRD analysis along with theoretical model can tell the crystal formation of new compounds. I suggest that you may study the chemical states of the elements through XPS. Then you may be able to guess the compound.
Take care when using XRD for nanomaterials. The sensibility of this technique for solid particles is around 100 Angstrons (Cullity). Particles smaller than this size would be considered "amorphous", which could be an incorrect interpretation. So, the TEM analysis is very important in this case, combined with EDS/WDS as Dr. Derenzo said. Perhaps a traditional chemical analysis for the sample digested in HF combined with atomic absorption can indicate the approximate stoichiometry of the elements in the solid and help in understanding the structure formed. That is, combined techniques will bring a better understanding of your nanomaterial.
