Energy efficient green synthesized MOF-801 for adsorption cooling applications

Utilization of water as a refrigerant in adsorption cooling systems is a challenging task due to the unavailability of suitable adsorbents. Recently, a new class of porous material, metal–organic frameworks (MOFs), is heightening interest as the potential adsorbent for water adsorption due to its crucial S-shaped adsorption isotherm characteristics. Additionally, the high surface area, large pore volume, and higher affinity towards water vapor outshined MOFs over other porous materials to be used as adsorbent in water-based adsorption cooling system (ACS). However, their industrial production could be obstructed due to economic and ecological limitations. Therefore, in this study, an energy-efficient, environment friendly, rapid and ultrasonication assisted room temperature green synthesis procedure for MOF-801 is reported with additional finding of optimum synthesis condition. Several characterization techniques are employed to ensure the structural stability of the synthesized MOFs and their applicability in ACS. The reaction time of the green synthesized MOF-801 was reduced by eight times than the conventional one while ensuring excellent system performance, which makes this process promising for industrial production.
