Popis: A new and versatile binder-based metal organic framework-(MOF-) coating enables efficient use in fast-cycle adsorption chillers for cooling and refrigeration applications. Two different adsorbents were presented, HKUST-1 and Mil-101(Cr), with promising methanol adsorption characteristics and high loading capacities up to 1.22 g g −1 . Polysiloxane-based coatings containing 65 and 80 wt% of the MOF adsorbents were produced and the adsorption characteristics were studied before and after extensive thermal treatment over 1000 cycles between 20 °C and 130 °C under methanol atmosphere by thermogravimetric analysis and X-ray diffractometry. Using the Dubinin-Astakhov approach, possible methanol loading lifts in a refrigeration process under different application conditions were quantified.
