Abstract
- Abstract: Hydrogen and deuterium adsorption sites in the crystalline MOF copper(II) benzene-1,3,5-tricarboxylate, Cu–BTC were studied by low-temperature thermal desorption spectroscopy. For a maximum loading of 218 D2 molecules per unit cell of Cu–BTC three desorption maxima were observed. The maxima could be separated by either interrupted desorption or partial loading. By comparing to neutron diffraction studies from the literature the maxima could be assigned to three different adsorption sites, i.e. coordinatively-unsaturated Cu2+ sites, tetrahedral side pockets and the large pores.
