Desorption Studies of Hydrogen in Metal-Organic Frameworks

The diameter is decisive: Adsorption sites for hydrogen in the metal–organic frameworks Cu‐BTC, MIL‐53, MOF‐5, and IRMOF‐8 could be identified by using thermal desorption spectroscopy at very low temperatures (see graph). The correlation between the desorption spectra and the pore structure of these...

Zusammenfassung:The diameter is decisive: Adsorption sites for hydrogen in the metal–organic frameworks Cu‐BTC, MIL‐53, MOF‐5, and IRMOF‐8 could be identified by using thermal desorption spectroscopy at very low temperatures (see graph). The correlation between the desorption spectra and the pore structure of these MOFs shows that at high hydrogen concentrations the diameter of the cavity determines the heat of adsorption.
