Metal-organic frameworks (MOFs) are a family of permanently nanoporous materials with tailorable pore size and geometries, which show promise for a wide range of applications including selective gas storage, selective separation, catalysis, and drug delivery. In particular, as concerns for climate change continue to increase, and fossil fuels continue to be depleted, MOFs have received significant attention regarding their use as a high density gas adsorbent for carbon capture and storage (CSS) and sustainable energy storage. However, MOFs have been severely limited by their low stability in air, and incompatibility with liquid systems. Whilst research has predominantly focused on the development of crystalline MOFs in the solid-state, recent advances in the field of porous liquids has shifted attention to the exploration of liquid MOF phases. This PhD project therefore aims to firstly explore methods of preventing MOF degradation in air, and secondly aims to develop a liquid-MOF system. The development of novel porous liquids analogous to air-stable solid-state MOFs could enable selective adsorption in liquid systems, whilst also presenting the advantages of rapid mass transfer, fast kinetics, and fluidity. The implementation of such MOFs has huge potential in storing hydrogen as a clean energy carrier with improved efficiency, and is of upmost importance for the removal of carbon dioxide from industrial processes to limit global warming to 1.5C.

金属有机框架（MOF）是一个具有可定制孔径和几何形状的永久性纳米多孔材料的家族，对广泛的应用显示了有望，包括选择性气体存储，选择性分离，催化和药物输送。特别是，随着对气候变化的担忧继续增加，化石燃料继续耗尽，MOF对它们用作碳捕获和储存（CSS）和可持续能源存储的高密度气体吸附剂的使用非常关注。但是，MOF在空气中的稳定性低以及与液体系统不兼容受到严重限制。尽管研究主要集中在固态中晶体MOF的发展上，但多孔液体领域的最新进展已将注意力转移到探索液体MOF相的探索。因此，该博士学位项目旨在首先探索防止空气中MOF降解的方法，其次是旨在开发液体MOF系统。与空气稳定的固态MOF相似的新型多孔液体的发展可以在液体系统中具有选择性的吸附，同时还具有快速传质，快速动力学和流动性的优势。这种MOF的实施在将氢作为具有提高效率的清洁能源载体方面具有巨大的潜力，并且对于将二氧化碳从工业过程中除去以将全球变暖限制为1.5C至关重要。
