Inverse ZrO2/Cu as a highly efficient methanol synthesis ... - Nature
Nov 13, 2020 · In situ XRD-PDF, XAFS and AP-XPS structural studies reveal that the inverse ZrO 2 /Cu catalysts are composed of islands of partially reduced 1–2 nm amorphous ZrO 2 supported over metallic Cu...
XAFS and XRD Analysis of Ceria–Zirconia Oxygen Storage
Nov 3, 2007 · We investigated the local structure around both Ce and Zr in these CeO 2 –ZrO 2 samples using X-ray absorption fine structure (XAFS) in order to determine the cation–cation (cation = Ce, Zr) network and the oxygen environment around the cation [12, 13].
XAFS study of Zr site preference for Nd - ScienceDirect
Apr 1, 2000 · XAFS results reveal that Zr preferentially occupies Fe (j 2) and Fe (j 1) sites in the Nd 2 Fe 14 B structure for the disproportionated, partially and fully recombined states. The partially recombined sample shows larger magnetic anisotropy but a smaller coercivity than the fully recombined one.
The local structures of tektites and natural glasses were studied by Zr K–edge X–ray absorption near edge structure (XANES) and extended X–ray absorption fine structure (EXAFS) measurements in order to obtain quantitative data on the Zr–O (bonding) distances and coordination numbers for the glasses.

Feb 1, 2015 · The local structures of tektites and natural glasses were studied by Zr K-edge X-ray absorption near edge structure (XANES) and extended X-ray absorption fine structure (EXAFS) measurements in...
Multimodal analysis of Zr substitution effects on magnetic and ...
Jan 1, 2023 · X-ray absorption fine structure (XAFS) and scanning transmission electron microscopy indicated a selective occupation of the Sm site by Zr atoms without disturbing the Fe sublattices.
In situ XAFS–XRD study of the Zr–Y2O3 interaction at extra-high ...
May 31, 2024 · In the present study, we focus on the in situ XAFS–XRD technique to investigate the high-temperature interaction (above 2000 K) of Zr–Y 2 O 3 mixture by additionally installing XRD apparatus to the XAFS measurement system developed by one of …
High-Pressure XAFS Study of Pure ZrO2 and Stabilized Cubic ZrO2
X-ray absorption fine structure (XAFS) measurements near the Zr K-edge for pure ZrO 2 and stabilized cubic ZrO 2 (+8% Y 2 O 3 ) were performed under pressure up to 7.8 GPa using a multi-anvil high-pressure device and synchrotron radiation at BL14B1, SPring-8, Hyogo.
Initial XAFS results show clear differences between spectra of Zr in an HCl solution and in an H2O-Na2Si2O5 aqueous fluid, implying considerable differences in the Zr complexation.
