The decomposition behavior of H2PtCl6 or Pt(NH3)4Cl2 supported on amorphous silica was investigated by X-ray absorption near edge spectroscopy using a laboratory-type spectrometer. The choice of a monochromator crystal, the slit width and the acquisition time for in situ measurements of catalyst sam...
