17O Solid-State NMR spectra of ceria nanocubes. The 17O NMR measurements were performed at a spinning speed of 20 kHz for NCs-17O2 (a) and 16 kHz for NCs-H217O (b). A rotor synchronized Hahn-echo pulse sequence (π/6-τ-π/3-τ-acquisition) with 1H decoupling and a 0.5 s recycle delay was used. Stars denote spinning sidebands. In order to show the peaks due to OH better, a line broadening of 600 Hz is applied for the enlarged spectrum shown in light blue region.
