Abstract

We report a series of Pd K-edge and Pt L ₃-edge X-ray absorption spectra (XAS) collected in situ during thermal treatment of functionalized UiO-67-Pd and UiO-67-Pt metal-organic frameworks in inert and reducing atmospheres. We present raw synchrotron data from three subsequent experiments at different beamlines, normalized XAS spectra and k ²-weighted oscillatory χ(k) functions extracted from one of the datasets. Pd K-edge spectra were collected for the samples in 5% H₂/He, 3% H₂/He and pure He in the temperature range from room temperature (RT) to 450 °C. Pt L ₃-edge were collected for the samples in 3% H₂/He, 10% H₂/He and pure He in the temperature range from RT to 300 °C. All spectra are reported together with the used atmosphere and temperature. For the analysis of all reported datasets, please see "Evolution of Pt and Pd species in functionalized UiO-67 metal-organic frameworks". Fourier-analysis of Pd K-edge is reported in "Formation and growth of Pd nanoparticles in UiO-67 MOF by in situ EXAFS".
