Figure 8
Normalized Ti K-edge XANES spectra for TiO2 powder measured at room temperature, 373 K, 473 K, 573 K, 623 K, 673 K and 723 K during heating. Also shown are the reference spectra for the anatase and rutile phases measured at room temperature. The inset figure shows the pre-edge peaks of the Ti K-edge XANES spectra taken at 633 K, 643 K, 653 K and 663 K. |
