SAMCat - From Active Site to Catalytic Material

The SAMCat team is specialized in the development of catalytic and electrocatalytic materials for applications mainly in the fields of energy (new fuels, production and use of hydrogen, etc.) and the environment (waste gas and water treatment, etc.).

 

Research Axis

The team is structured around 3 research axes.

 

 

Dedicated Materials and Characterizations axis

  • Nanomorphological control of materials with modular redox and/or acid-base propertiesThe main types of materials studied are solid or supported metals, simple or mixed metal oxides, nanostructured solids (2D and 3D) and zeolites, and more recently also inorganic oxyhydroxyfluorides of large specific surface area and with modular acid-base properties.
  • Development of specific ex-situ, in situ and operando analysis toolsResearch on specific characterization tools is carried out to enable an accurate description of the entire catalytic process (reaction mechanisms, description of active sites on the catalyst surface).

Catalysis and Electrocatalysis for Energy axis

  • Study of materials with optimized properties for energy conversion and storage systems.
  • Use of catalysis, electrocatalysis and photoelectrocatalysis in various systems (catalytic reforming, ammonia synthesis, catalytic dehydrogenation, fuel cells, ion exchange membrane electrolysers, organic and mineral electrosynthesis, etc.).
  • Hydrogen vector (production, use, storage).
  • Conversion of biomass and natural gas into energy carriers or products of interest.
  • (Electro)activation of greenhouse gases.
  • Development of innovative, efficient and environmentally friendly space propulsion systems.

Environmental Remediation Axis

  • Study of materials with optimized properties (active sites, porosity) for depollution.
  • Treatment of mineral or organic pollutants, in the gaseous (atmospheric) or liquid phase, by catalytic reaction and/or adsorption.
  • (Electro) Activation of greenhouse gases.
  • Treatment and recovery of waste.

Skills

Some examples of specific characterization tools developed within the SAMCat team

  • Monitoring by IRTF absorption spectrophotometry of the transformation and/or adsorption of molecules (with or without potential control) on the surface of the catalyst, with possible coupling to a mass spectrometer
  • Characterization by reaction models of metal function, acid-base or hydrophobic properties, complementarity and distance between acid and metal sites
  • Measurement of intra- or extra-network diffusion by isotope exchange/mass spectrometry coupling
  • Measurement of adsorption kinetics in confined environments by RF-GC chromatography
  • Coke characterization by MALDI-TOF/MS, LDI-TOF/MS
  • Measurement of oxygen storage capacity (OSC)
  • Hydrophobicity index
