We study the electronic structure of three-dimensional nanoporous CeO_2-x monoliths (aerogels) by soft x-ray absorption near-edge structure (XANES) spectroscopy. Atomic multiplet calculations are used to interpret high-resolution Ce0.2em0exM4,5- and N4,5-edge XANES spectra. Results show that aerogels with thicker ligaments, but with the same average size of crystallites, exhibit larger Ce³⁺ content and, hence, higher oxygen deficiency.
