Characterization of porous materials

A successful application of adsorptive/catalytic processes essentially depends on the selection of the appropriate functional material. In addition to the use of classical physisorption and breakthrough experiments, new measurement methods are being developed at the IWS, which focus on fast, simple and cost-effective screening of functional materials.

• recording of static adsorption isotherms by gravimetric and volumetric physical adsorption methods
• characterization of adsorber materials with regard to general adsorption parameters, for example, specific surface area, pore volume, pore size, N₂-physisorption, Hg-porosimetry
• characterization of potential materials with respect to dynamic adsorption capacity and kinetics by means of breakthrough measurements
• rapid screening of functional materials with regard to their gas adsorption capacity and specific surface area (INFRAsorp)
