The open adsorption property is the ability of adsorbent to absorb water vapor in atmosphere. This paper reports MIL-101(Cr) was synthesized with sodium acetate as mineralization agent, and MIL-101(Cr) was purified using DMF and ethanol, which used as a high efficient adsorbent for water abstraction. The morphology and the pore structure of the as-prepared product were systematically discussed through N₂ adsorption-desorption analysis and Scanning electron microscopy (SEM). And its thermal stability performance was measured by Thermogravimetric (TG), the heating temperature is too high, the material structure easily damaged. Besides, SEM images shows that the MIL-101(Cr) crystals are regular shaped octahedrons. The N₂ adsorption-desorption analysis shows that MIL-101(Cr) possessed microspore, which was benefit for the water adsorption. In addition, the experiment studied the optimal activation temperature, MIL-101 has the highest adsorption performance after activation at 140 °C. Finally, the water adsorption and recycling performance of MIL-101(Cr) were investigated. And recycling performance showed that desorption residual amount was lower than 9% of the total equilibrium adsorption capacity after 10 cycles. It is envisaged that MIL-101(Cr) will be a promising adsorbent for the freshwater production in coastal areas by extracting water from atmosphere.

开放的吸附性能是吸附剂在大气中吸收水蒸气的能力。本文报道了用乙酸钠作为矿化剂合成MIL-101（Cr），并使用DMF和乙醇将其纯化为MIL-101（Cr），将其用作提取水的高效吸附剂。通过N ₂吸附-脱附分析和扫描电子显微镜（SEM），系统地讨论了所制备产品的形貌和孔结构。并且其热稳定性能通过热重法（TG）测量，加热温度过高，材料结构易损坏。此外，SEM图像显示MIL-101（Cr）晶体是规则形状的八面体。N ₂吸附-解吸分析表明，MIL-101（Cr）具有微孢子，有利于水的吸附。此外，实验研究了最佳的活化温度，MIL-101在140°C活化后具有最高的吸附性能。最后，研究了MIL-101（Cr）的吸水和循环利用性能。循环性能表明，经过10个循环后，解吸残留量低于总平衡吸附量的9％。可以设想，MIL-101（Cr）通过从大气中提取水，将成为沿海地区淡水生产的有希望的吸附剂。
