“…As shown in Figure 3a, PGF delivers the rapid moisture sorption with an equilibrium water uptake of 5.20 g g −1 at an RH of 100%, much higher than that of pure rGO and PAAS foam with the value of 0.26 and 1.29 g g −1 , respectively. Compared with previous reports (Table S1, Supporting Information), [13][14][15][16][24][25][26][27][28][29][30][31][32][33][34] PGF in this study shows an outstanding ability for moisture capture in the full range of humidity, which will largely broaden the applications in diverse environments. The microporous structure of PGF provides effective transport channels and an enlarged contact area for moisture, and oxygen functional groups of PAAS can spontaneously capture water molecules through hydrogen bonding ( Figures S3 and S4, Supporting Information).…”

contaminated inevitably by the impurities, such as microorganisms, fine particulate matters (PM), and toxic gases like sulfur oxides (SO x ). [11,12] Recently, miscellaneous hygroscopic materials have been explored for moisture capture. For instance, metalorganic frameworks (MOFs) like MOF-801 could harvest 0.25 g g −1 water at a relative humidity (RH) of 20%, and poly(Nisopropyl acrylamide)/sodium alginate (PNIPAAm/Alg) polymer hydrogel demonstrated 0.6 g g −1 water uptake at the RH of 80%, respectively. [13][14][15][16] However, MOF-801 only worked in a narrow RH range (<20% RH) with low water uptake, and the quality of the oozed water from PNI-PAAm/Alg hydrogel was uncertain for the risk of impurities. As a result, it is still a big challenge for harvesting high-quality clean water free of impurities from the air within a full range of humidity.Herein, we demonstrate a highly efficient clean water production system from a contaminated environment with a wide range of humidity based on a rationally designed sodium polyacrylate (PAAS)/graphene framework (PGF). This porous framework with plentiful oxygen functional groups facilitates the sorption of water vapor in humid air and simultaneously grabs the impurities under van der Waals force (Figure 1). Moreover, a high solar-thermal conversion capability of PGF makes water easily desorbed under sun irradiation. [2,17,18] As a result, such a PGF presents the equilibrium water uptake of 0.14 g g −1 at a low RH of 15%, and a superhigh uptake of 5.20 g g −1 at an RH of 100%, exhibiting the excellent water uptake ability in a wide range of humidity. Under solar irradiation of 1 sun (1 kW m −2 ), the sorbed water can be quickly desorbed into vapor within a few minutes to generate clean water free of impurities. Thus, the PGF meets the requirements of efficient moisture capture, impurities filtration, and clean water production from natural air. For practical application, a lab-made prototype of moisture purification and water harvest (MPWH) system is built to collect over 25 L clean water per kilogram of PGF daily from the atmospheric environment. This PGF offers an efficient platform to capture moisture in ordinary and contaminated air for the production of high-quality clean water.The porous PGF is easily prepared through a convenient freeze-drying method (see details in Materials and Methods, Supporting Information). Typically, PAAS is well dispersed in a graphene oxide (GO) dispersion after ultrasonic treatment (Figure 2a). After the freeze-drying (Figure 2b) and reductionThe huge amount of moisture in the air is an unexplored and overlooked water resource in nature, which can be useful to solve the worldwide water shortage. However, direct water condensation from natural or even hazy air is always inefficient and inevitably contaminated by numerous impurities of dust, toxic gas, and microorganisms. In this regard, a drinkable and clean water harvester from complex contaminated air with a wide humidity range based on porous sodium polyacrylate/graphene framework (PGF...

The energy-storage capacities of a series of water-stable porous metal-organic frameworks, based on high-valence metal cations (Al , Fe , Cr , Ti , Zr ) and polycarboxylate linkers, were evaluated under the typical conditions of seasonal energy-storage devices. The results showed that the microporous hydrophilic Al-dicarboxylate MIL-160(Al) exhibited one of the best performances. To assess the properties of this material for space-heating applications on a laboratory pilot scale with an open reactor, a new synthetic route involving safer, greener conditions was developed. This led to the production of MIL-160(Al) on a 400 g scale, before the material was shaped into pellets through a wet-granulation method. The material exhibited a very high energy-storage capacity for a physical-sorption material (343 Wh kg ), which is in full agreement with the predicted value.

Abstract.A new rigid metal-organic framework (MOF) with MIL-53 topology built of 2,5-thiophenedicarboxylate (TDC) and Al, Ga, or In is reported. Its structure contains chains of trans corner sharing MO 6 octahedra, connected by the linker molecules to form microporous square shaped 1D channels. A combination of powder X-ray diffraction (PXRD), density functional theory (DFT) calculations, and 1 H, 13 C, and 27 Al solid-state NMR spectroscopy (ssNMR) was used to analyse the structures in detail. The synthesis is easily scaled-up using microwave assisted solvothermal conditions. All materials possess a
