The high surface areas and tunable properties of Zr-based MOFs make them as attractive materials for gas capture, storage, and separation. In this work, UiO-66, one kinds of Zr-based MOFs, functionalized by single or binary –NO₂ and –NH₂ groups are synthesized. Water adsorption ability and hydrophilicity of UiO-66 and functionalized UiO-66-X were investigated. It is found that surface area of UiO-66 is decreased after introducing functional groups, while hydrophilicity of UiO-66 increased after functionalized with –NO₂ and –NH₂. Therefore, after balance the effects of surface area and hydrophilicity, UiO-66-NH₂ shows the best water adsorption propriety.

Zr基MOF的高表面积和可调性使其成为用于气体捕获，存储和分离的有吸引力的材料。在这项工作中，合成了UiO-66，这是一种通过单或二元–NO ₂和–NH ₂基团官能化的Zr基MOF 。研究了UiO-66和功能化UiO-66-X的吸水能力和亲水性。发现引入官能团后UiO-66的表面积减小，而用–NO ₂和–NH ₂官能化后UiO-66的亲水性增加。因此，在平衡表面积和亲水性的影响之后，UiO-66-NH ₂显示出最佳的吸水性能。
