Material Analysis of Four MOFs Applied to Adsorption-Based Atmospheric Water Harvesting in Desert Areas
The application of metal organic frameworks(MOFs)to the technology of adsorption-based atmospheric water harvesting(ABAWH)is an effective means to solve the problem of atmosphere water harvesting under low humidity conditions.However,there are few systematic reviews on MOFs,and there is a lack of studies on the thermal stability and toxicology of MOFs.In this paper,a multi-dimen-sional evaluation system(physical properties,adsorption-desorption isotherm,water stability,thermal stability and toxicity)is established based on the research background of low humidity and high tempera-ture climate in a certain desert.The Analytic hierarchy process(AHP)is used to compare and study four MOFs materials(MOF-801,Aluminum fumarate,MIL-100 and CAU-10H).The main conclusions are as follows.(1)MIL-100 has obvious advantages in terms of specific surface area and adsorption-desorption performance.(2)Aluminum fumarate is best in terms of thermal stability,CAU-10H is better than MOF-801 and MIL-100.(3)In terms of safety,MIL-100 and MOF-801 are more reliable.It is concluded that MIL-100 is more suitable as adsorbent for ABAWH devices.
