- Abstract
We estimated the crystallinity and phase ratio of anatase to rutile in TiO2 nano-particles by Ti K-edge X-ray absorption near-edge spectroscopy (XANES) spectra. The nano-sized TiO2 powders prepared by the homogeneous precipitation process at low temperature (HPPLT) were compared with the commercial TiO2 powders with good crystallinity. From the comparison with the experimental and calculated Ti K-edge XANES spectra, we found the possibility of efficient estimation in the crystallinites and the phase ratio of anatase to rutile for nano-sized TiO2 mixtures.
