Fig. 2: 17O NMR data and surface structure.

From: Revealing the structure-activity relationship of Pt1/CeO2 with 17O solid-state NMR spectroscopy and DFT calculations

Fig. 2

17O solid-state NMR spectra of (a) PtnOx/CeO2, (b) PtLC/CeO2, and (c) PtHC/CeO2 and the summary of calculated NMR shifts (center of gravities) of O atoms connected directly to Pt, as well as the corresponding structures. The spectra were recorded at a spinning speed of 53 kHz with a recycle delay of 0.2 s at 14.1 T. A rotor synchronized Hahn-echo pulse sequence (π/6-τ-π/3-τ-acquisition) with 1H decoupling was applied. Asterisks denote spinning sidebands.
