Abstract
Atmospheric water harvesting (AWH) is considered to be a promising technology to address the issue of global water shortage. The adsorption-based AWH technology, showing the advantages of simple device structure, high energy efficiency, wide application range, etc., and thus has attracted wide attention. For the adsorption method, one of the key issues is to find high-performance porous adsorbents. Porous carbons display exceptional stability, high porosity and low cost. However, they are commonly highly hydrophobic and less affinitive toward polar water molecules. In this work, a class of monolithic porous carbons with impressive hydrophilicity was prepared by interpenetrating metal-organic frameworks into resorcinol-formaldehyde resin networks, in which the metal-organic parts evolved into polar sites in the final products. The AWH test showed that, in the relative humidity of 40-80%, the water capture capacity of the adsorbent can reach about 20 wt.%. The surface modification strategy can also provide a novel idea for the preparation of monolithic hydrophilic carbons for other applications.
