Project description
Water-stable solar atmospheric water harvesting in arid climates
Atmospheric water harvesting (AWH), which uses solar energy, encounters challenges in arid climates due to low relative humidity and the diminished efficacy of conventional sorbents. Metal-organic frameworks (MOFs) represent a type of porous material capable of capturing water even at very low RH levels. However, the combination of photothermal materials with MOFs can diminish the sorption capacity of MOFs, a particular issue in arid climates. With the support of the Marie Skłodowska-Curie Actions programme, the PHOTOWAT project will synthesise a water-stable MOF with photothermal and photocatalytic properties (PAMOF) and high water affinity. Molecular modelling and experimental synthesis will evaluate promising candidates, and an AWH device will assess the efficiency and maintenance of the samples under real conditions using a custom-made solar simulator.
Objective
Atmospheric water harvesting (AWH) using solar energy has gained significant attention; however, its application in arid climates poses challenges due to low relative humidity (RH) and reduced efficiency of conventional sorbents. metal-organic frameworks (MOFs) are a class of porous materials with an engineerable structure that have the ability to capture water even at very low RH. Usually, the combination of photothermal materials with MOFs is used to desorb water sorbed by MOFs. One of the challenges of this method is the reduction of MOF sorption capacity, which is very unfavorable, especially in arid climates. Reducing the performance of sorbents in arid climates due to the blocking of sorption sites by dust is another challenge that has received little attention so far. To address these challenges, this study evaluates the synthesis of a unique water-stable MOF with photothermal and photocatalytic (photoactive) properties (PAMOF), in addition to high water affinity. Phthalocyanine and porphyrin ligands decorated with Ti and Cu ions, along with Yttrium (Y) and Erbium (Er) clusters, are considered as promising candidates. Molecular modeling using density functional theory (DFT) will be conducted to guide the synthesis process, followed by experimental synthesis and characterization. Subsequently, the samples will be evaluated in an AWH device to assess short-term efficiency and long-term maintenance in real conditions. In addition to harnessing natural solar energy, the AWH experiments will involve the utilization of a custom-made solar simulator. The SAWH device will be evaluated across a range of RHs, spanning from 10% to 90%, while considering the presence of artificial dust. Through comparative analysis of existing research and with the aim of enhancing previously studied systems, this project endeavors to attain a daily water evaporation rate surpassing 4 kgwater/kgPAMOF under 1 sun and RH<30.
