As in XRD we can get the pattern of different phases but how the different phases of TiO2 can be seen?
Hi Huang,
Routinely you check with standard PDF (powder diffraction file) of different phases, like rutile/anatase/brookite, to see if your experimental XRD patterns match with one or more of them (or even amorphous state). You may have a look at following papers, just as a start point:
1. K. Sakurai and M. Mizusawa,X-ray Diffraction Imaging of Anatase and Rutile, Anal. Chem., 82,(2010)3519–3522.

2. L Miao et al., Preparation and characterization of polycrystalline anatase and rutile TiO2 thin films by rf magnetron sputtering, Applied Surface Science, 212–213 (2003) 255–263.

Hope this helps.
Best,
Yang
thanks for the responses. @Dr. Towe, I mean to ask that from XRD we can find the pattern for phases but can we see the isolated phases or composite phases by any other method which can confirm XRD pattern. Thanks
