An air conditioning system and method of air conditioning is provided. The air conditioning system includes an intake mechanism configured to draw into the air conditioner a first amount of air and an amount of moisture from an exterior of the air conditioner. The system further includes metal organic frameworks in fluid communication with the intake mechanism, the metal organic frameworks configured to adsorb the amount of moisture from the first amount of air. The system further includes an indirect evaporative cooler configured to cool the first amount of air. The system further includes a solar heater configured to heat a second amount of air. The system further includes a heat exchanger configured to contact the second amount of air with the metal organic frameworks to regenerate the metal organic frameworks.

Solar-driven membrane-based open-cycle adsorption air conditioner

Disclosed are MOFs containing nucleophilic transition metal hydroxide (M-OH) groups. In certain embodiments, these MOFs can include a plurality of metal ions, each coordinated with one or more hydroxide ligands and one or more backbone ligands. In certain embodiments, the MOFs can comprise Kuratowski cluster-based secondary building units (SBUs). These MOFs can exhibit excellent performance for low pressure COcapture via a CO/HCOfixation mechanism in which cooperative inter-cluster hydrogen bonding interactions enhance COcapture performance. Also provided are methods of making MOFs including one or more metal hydroxide moieties, as well as methods of using these MOFs to capture an acidic gas (e.g., CO, SO, NO, or acetylene).
