Analytical methods and facilities

Analytical methods

Our group makes an extensive use of the following characterization and analytical methods:

Characterization of catalysts
  • X-ray diffraction: powder XRD, including in situ XRD applications
  • Elemental analysis: ICP-MS, ICP-OES and XRF
  • Infrared spectroscopy: Raman and attenauted total reflection-FTIR
  • Thermal analysis: TGA
  • Porosimetry and chemisorption: BJH and BET
  • Surface analysis: XPS
  • Electron microscopy: SEM and TEM
  • Magnetic resonance: SS-NMR and SS-EPR
Characterization of reaction mixtures
  • Chromatography: GC-MS, HPLC, HPLC-MS
  • Magnetic resonance: 1H-NMR, 13C-NMR, and EPR, including variable temperature and under pressure

Research group facilities

  • In situ XRD cell for the investigation of solid state phase transitions under a variety of oxidizing or reducing atmospheres (up to 10 bar and 900 oC)
  • Chemisorption station for metal exposed fraction (via H2) and determination of acid sites (via NH3)
  • Tube furnace for hydrogenations and hydrothermal synthesis (up to 2 bar and 1000 oC, under flows of: air, N2, H2/N2 or under vacuum)
  • High pressure autoclaves for hydrothermal synthesis, and for chemical processes scale up (up to 200 bar and 250 oC)
  • Ovens and muffles in static air (up to 1000 oC)
  • Multi batch mid-low pressure reactors (up to 3 bar of: air, N2, O2 and 180 oC)
  • Fixed bed catalytic reactor for liquid phase via peristaltic pump (2 bar inlet up to 180 oC)
