27, rather than detectable amounts of the lattice oxygens with typical signal at 529–530 eV28 (green bar in Fig. 1f). The k3-weighted Ru K-edge R-space extended XAFS (EXAFS) spectra (Fig. 1e) and corresponding wavelet transform of the EXAFS spectra (Fig. 1g–i and Supplementary...
range. More importantly, operando XAS indicates that B can stabilize osmium in an electron-deficient state, contributing to the excellent activity and stability, and also reveals the mechanisms of B-Os aerogels in varied electrolyte environments, which is valuable for the rational design of future e...

Density functional theory calculations indicate that the electron-deficient sites show a much lower energy barrier (0.76 eV) for the potential determining step compared with that of the pristine NiFe-LDH (2.02 eV). Benefiting from this, the NiFe-LDH with oxygen vacancies exhibits the greatly ...

Crystallographic shear in oxygen-deficient rutile: An electron microscope studyElectron microscopy, electron diffraction, and direct lattice imaging show that extended defects are important in substoichiometric TiO 2. Planar faults on {132} in near-stoichiometric TiO 2 are identified as shear planes, of...
XPS results show that under the EB irradiation, nitrogen ions have been doped into the TiO 2 lattice successfully, as well as part of Ti 4+ on the surface of the samples changed to Ti 3+ . Photocatalytic performance was tested by decomposing Rhodamine B in the aqueous phase under visible ...
