The water crisis is one of the main global risks based on its societal impact, particularly the access to safe drinking water in regions with a dry (arid) or mainly dry (semi-arid) climate. Several techniques are being developed, namely the use of regenerative desiccant (e.g., MOFs) to water capture through adsorption processes. MIL-160(Al) belongs to the fumarate-based MOFs family, and it is one of the most promising MOFs for water harvesting and heat transformation applications. In this study, the potential of MIL-160(Al) as an adsorbent for water sorption based applications was evaluated. For this purpose, adsorption equilibrium isotherms, dynamic adsorption experiments, and MIL-160(Al) granules characterization were performed. H₂O vapor adsorption equilibrium isotherm was studied at 303, 323, and 343 K presenting a type V shape and was fitted using the Cooperative Multimolecular Sorption model and Polanyi’s theory model. Additionally, CO₂, N₂, and O₂ adsorption equilibrium isotherms were also measured but at 283, 303, and 323 K, presenting the following order of adsorption affinity: CO₂ > O₂ > N₂. Water vapor adsorption breakthrough experiments corroborate the shape of the water adsorption equilibrium isotherms on MIL-160(Al). Water co-adsorption history proved that the presence of the other air components (CO₂, O₂, and N₂) does not affect water adsorption behavior on MIL-160(Al). DRIFTS measurements proved the MIL-160(Al) structure remains stable during the water vapor exposure. The optimization of the TSA process allowed us to achieve maximum H₂O productivity of 305 L·day⁻¹·ton⁻¹ for a regeneration temperature of 353 K and flow rate equal to 0.50 m³·s⁻¹.

基于其社会影响，水危机是主要的全球风险之一，尤其是在干旱（干旱）或主要干旱（半干旱）的地区获得安全饮用水的情况。正在开发几种技术，即使用再生干燥剂（例如，MOF）通过吸附过程捕集水。MIL-160（Al）属于基于富马酸酯的MOF系列，是集水和热转化应用中最有前途的MOF之一。在这项研究中，评估了MIL-160（Al）作为基于水吸附应用的吸附剂的潜力。为此，进行了吸附平衡等温线，动态吸附实验和MIL-160（Al）颗粒表征。高₂研究了在303、323和343 K处呈V型的O蒸气吸附平衡等温线，并使用合作多分子吸附模型和Polanyi理论模型进行了拟合。另外，还测量了CO ₂，N ₂和O _2的吸附平衡等温线，但在283、303和323 K时，表现出以下吸附亲和力顺序：CO ₂  > O ₂  > N ₂。水蒸气吸附突破实验证实了MIL-160（Al）上水吸附平衡等温线的形状。水的共吸附历史证明存在其他空气成分（CO ₂，O ₂和N ₂）不会影响MIL-160（Al）上的水吸附行为。DRIFTS测量证明，在暴露于水蒸气期间，MIL-160（Al）结构保持稳定。TSA工艺的优化使我们能够在353 K的再生温度和等于0.50 m ³ ·s ^-1的流速下实现305 L·day ^-1 ·ton ^-1的最大H ₂ O生产率。
