| Abstract: | Pt-Au nanostructures are important and well-studied fuel cell catalysts for their promising catalytic performance. However, a detailed quantitative local structure analysis, using extended X-ray absorption fine structure (EXAFS) spectroscopy, have been inhibited by interference between Pt and Au L-3-edges. In this paper, Pt L-3-edge XAFS analysis, free of Au L-3 edge, is demonstrated for a Pt-Au reference sample using a low-cost log-spiral bent crystal Laue analyzer (BCLA). This method facilitates the EXAFS structural analysis of Pt-Au catalysts, which are important to improve fuel cell catalysts. |
