This work demonstrates the high potential of MOFs serving as a sensor material for the detection of low water vapour concentration (ppm). Thin HKUST-1 MOF-coatings were characterized by FT-NIR and UV/Vis-spectroscopy during the adsorption of water vapour at different concentration levels.

The adsorption/desorption of up to 0.75 g of water vapour per g of the porous MOFs 3D-{M3O(X)(H2O)2[btc]2·nH2O}, MIL-100 (M = Al, Fe; X = OH, F, btc = benzene-1,3,5-tricarboxylate, trimesate), occurs at small relative pressures of p/p0 < 0.4 and a comparatively small hysteresis. Together with very good cycle stability, these properties render both MIL-100(Al and Fe) very suitable candidates for thermally driven heat pumps or adsorption chillers.

A new tool (Infrasorb-12) for the screening of porosity is described, identifying high surface area materials in a very short time with high accuracy. Further, an example for the application of the tool in the discovery of new cobalt-based metal–organic frameworks is given.

Water Adsorption Characteristics of MIL-101 for Heat-Transformation Applications of MOFs

Eur. J. Inorg. Chem. 2011, 471–474.

The adsorption of water vapor in the highly porous metal-organic framework (MOF) of 3D-[Cr3F(H2O)2O(bdc)3·~25H2O] (MIL-101) (bdc = benzene-1,4-dicarboxylate, terephthalate) of up to 1 g of water per gram of sorbent material (between 140 °C and 40 °C under a water vapor pressure of 5.6 kPa) together with the stability over several cycles makes MIL-101 the most promising material, so far, for heat transformation applications like thermally driven heat pumps or adsorption chillers.
