X-ray absorption spectroscopic measurements were carried out at the storage ring DORIS III (HASYLAB DESY, Hamburg, Germany) at the EXAFS II beam line, which was equipped with a Si (111) double-crystal monochromator. All spectra were recorded at room temperature in a step-scanning mode. For data analyses the program WinXAS [17] was used.

Quick EXAFS measurements were performed at the HASYLAB synchrotron (station XI. 1) in Hamburg, Germany. The measurements were done in transmission mode using ion chambers filled with a mixture of Ar and N2 to have an absorption of 20% in the first and of 80% in the second ion chamber. The monochromator (a double Si-111 crystal) was detuned to 50% at maximum intensity to avoid the presence of higher harmonics in the X-ray beam. In QEXAFS mode, the monochromator is in continuous motion. 

The XAS spectra of the Pt/LTL and Pt/K-Si02 samples were taken at the SRS laboratories (station 9.2) in Daresbury, UK, the spectra of the Pt/Cl-Al203 samples were taken at the ESRF (BM 29) in Grenoble, France and at the HASYLAB (XI. 1) in Hamburg, Germany. These measurements were done in transmission mode using ion chambers filled with Ar to have an...

R. Frahm and L. Troger made possible the realization of experiments at the EXAFS II and ROEMO II stations in HASYLAB at synchrotron DESY in Hamburg, Germany. 

The SAXS experiments were performed at the beamUne A2 of the DORIS 111 storage ring at the Synchrotron radiation facility HASYLAB/DESY (Hamburg, Germany). The samples were filled in glass mark tubes of 1 mm diameter. The X-ray beam wavelength, X, was 1.5 A. The scattered intensity was recorded using a one-dimensional (ID) detector, which area was divided into 1024 pixels. The ID SAXS data were calibrated by a rat-tail tendon (RTT) standard.

Some measurements were performed using an X-ray source with rotating anode and a pinhole collimation [5]. The rest of the measurements were carried out using the synchrotron radiation generated at the beamline A2 of HASYLAB in Hamburg, Germany. The intensity was measured by means of one- and two-dimensional position-sensitive detectors, respectively.
