Hydrogen Storage
Hydrogen Storage Group
Studying and characterizing the gas—solid interactions for novel nanoporous materials is a pre-requisite for any future application in gas storage or separation. Therefore, we are developing and constantly improving state-of-the-art high-precision techniques to measure adsorption and desorption of gases over a wide pressure and temperature range starting as low as 20 K.

Hydrogen isotope separationHydrogen isotope mixtures can be separated using porous materials by either confinement in small pores i.e. |
 |
Hydrogen storageMetal-organic frameworks (MOFs) are a new class of porous materials that can store high amounts of molecular hydrogen via physisorption owing to their large specific surface area and ultra-high porosity. |
 |
Low-temperature adsorptionLow-temperature high-resolution adsorption isotherms of hydrogen isotopes are used to characterize pore structure, surface area and different adsorption sites. |
 |
Low-temperature thermal desorption spectroscopy TDSThermal desorption spectroscopy has been extended down to 20 K. |

Pressure composition isotherm PCTHydrogen high-pressure concentration isotherms (PCT) can be measured on only 100 mg sample mass precisely and reproducibly in dependence of pressure and temperature. |
