Methods

CAT Beamline
Available Methods, Obtainable Parameters

The CAT beamline offers  hard X-ray spectroscopy for in-situ and in-operando studies including the following methods:

X-ray Absorption Spectroscopy for elements between K and Er:

  • Information about the local atomic geometry (EXAFS)
  • Chemical state of the absorbing atom (XANES)
  • Investigations on ordered (crystalline) and disordered (amorphous, liquid) materials
  • Dilute species and light elements (XAS in fluorescence mode)
  • In situ and operando cells for measurements under reaction conditions

Under Construction/planned:

Fluorescence Spectroscopy:

  • High sensitivity for low concentrations
  • XAS measurements in fluorescence mode, X-ray Emission Spectroscopy

Diffraction experiments investigation of longe range order, crystalline phases and crystallite sizes, support materials

Infrared Spectroscopy

  • Analysis of species adsorbed on catalyst surfaces
