高内相乳液（HIPE）体系的设计无论从理论研究还是从实际应用的角度来看都是一个很有意义的课题。在这里，我们首次展示了利用金属有机框架（MOF）的HIPE形成。在室温下搅拌水、油和MOF的混合物，可以形成由MOF纳米晶在油-水界面组装而稳定的HIPE。MOF稳定的HIPE提供了一种制备高度多孔的金属有机气凝胶（MOA）单体的新途径。在去除MOF稳定的HIPE中的液体后，获得了密度低至0.01 g·cm− 3的超轻MOA。HIPE法制备金属氧化物避雷器具有独特的优点，可用于制备各种超轻金属氧化物避雷器，其孔隙率和结构可调。
To design high-internal-phase emulsion (HIPE) systems is of great interest from the viewpoints of both fundamental researches and practical applications. Here we demonstrate for the first time the utilization of metal-organic framework (MOF) for HIPE formation. By stirring the mixture of water, oil and MOF at room temperature, the HIPE stabilized by the assembly of MOF nanocrystals at oil-water interface could be formed. The MOF-stabilized HIPE provides a novel route to produce highly porous metal-organic aerogel (MOA) monolith. After removing the liquids from the MOF-stabilized HIPE, the ultralight MOA with density as low as 0.01 g·cm−3was obtained. The HIPE approach for MOA formation has unique advantages and is versatile in producing different kinds of ultralight MOAs with tunable porosities and structures.
