Water capturing from air is a promising technology to solve the shortage of freshwater resources. In this paper, metal organic framework (MOF-801)/graphene oxide (GO) composite membranes were prepared for efficient water capturing from air, and the effects of drying methods of membranes, MOF-801 contents, adsorption kinetics, and membranes reusability were investigated. The results showed that the natural-dried MOF-801/GO membranes displayed higher water vapor uptake than that of freeze-dried. The water vapor uptake of the membranes rose with the increased MOF-801 contents, and reached 0.23 g g(-1) (or 73 g m(-2)) at 30 % relative humidity and 17 degrees C for the MOF-801/GO (mass ratio of 3:1) membranes. The adsorption kinetics showed that the water vapor uptake rose quickly at first, and attained plateau after 4 h. The MOF-801/GO membranes displayed dehumidification rate of 98.68 % and excellent reusability, demonstrating great potential in water capturing from air.
