The applications of three-dimensional superstructures that consist of metal-organic framework (MOF) crystals are promising, but limited by spatial control over the crystallization process. Here a hydrophobic hierarchical metal-organic framework (HZIF-8) containing unusual micro-, meso-, and macropores was designed and synthesized by a template strategy, in which the polystyrene (PS) not only acted as the template to construct the macropores, but also modified the hydrophilic crystal surface of ZIF-8. When used as adsorbent for liquid oil/water separation, HZIF-8 demonstrated significantly enhanced oil adsorption performance while maintaining very low water uptake.
由金属有机框架（MOF）晶体组成的三维超结构具有广阔的应用前景，但受到结晶过程空间控制的限制。本文通过模板策略设计并合成了一种具有独特微孔、介孔和大孔的疏水性分级金属有机框架（HZIF-8），其中聚苯乙烯（PS）不仅作为构建大孔的模板，还修饰了ZIF-8的亲水晶表面。当用作液体油/水分离的吸附剂时，HZIF-8在保持极低吸水率的同时，表现出显著增强的油吸附性能。
