Abstract

Crystalline Au2O3 was obtained by hydrothermal synthesis at 3000 atm and its extended X-ray absorption fine-structure (EXAFS) at the Au L3-edge was measured at room temperature. A detailed full multiple scattering (MS) analysis using FEFF8 theory shows that only a small number of scattering paths contribute significantly to the EXAFS of Au2O3. Because of the complex unit cell (low local symmetry) of the Au2O3 structure, contributions of MS paths are almost negligible. The results indicate that FEFF8 theory provides a good reference for the analysis of Au-O phases. © 2003 Elsevier Science Ltd. All rights reserved.
