Water Stability and Adsorption in Metal-Organic Frameworks

A study was conducted to provide a review of water adsorption behavior in metal-organic frameworks (MOF). The investigations focused on a full classification of features that contribute to water stability, including thermodynamic and kinetic factors, applying these classifications to existing MOFs and discussing synthetic techniques and approaches for understanding and improving the water stability of future MOFs. Another option was to perform the water adsorption measurements by introducing a set partial pressure of water vapor into a system under vacuum. The majority of MOFs were microporous, and adsorption of many permanent gases followed the expected type I isotherm classification. The shape of an adsorption isotherm provided details on the strength and type of interaction between the adsorbate molecule and adsorbent surface.
