MIL-100(Al, Fe) as water adsorbents for heat transformation purposes-a promising application

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)center dot nH(2)O}, MIL-100 (M = Al, Fe; X OH, F, btc benzene-1,3,5-tricarboxylate, trimesate), occurs at small relative pressures of p/p(0) < 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.
