XANES spectra for Ce(NO 3 ) 3 ·6H 2 O and CeO 2 standard and pure CeO 2 and Gaussian fitting of XANES spectra. (a) XANES spectra at the Ce L3 absorption edge for Ce(NO3)3·6H2O and CeO2 standard showing features of A, B, C, and D. (b) XANES spectra of pure CeO2 at various hydrothermal treatment durations and temperature before and after annealing in Ar. (c) A Gaussian fitting of XANES spectra of pure CeO2 prepared at 20°C for 24 h.
