Water adsorption characteristics of MIL-101 for heat-transformation applications of MOFs

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.
