Experimental XANES spectra of Ti atoms in 8% Ti-GDC and simulated XANES spectra of Ti atoms in M1 (Ti replaces Ce in CeO2), M2 (CeTi2O6), M3 (Ce2Ti2O7), M4 (Ce2TiO5) and M5 (CeTiO3). The structure files for M1–M5 were obtained from the Materials Project database (Petousis et al., 2017; Munro et al., 2020; Patel et al., 2019; Jain et al., 2013) and rendered using VESTA (Momma & Izumi, 2011). |
