A key barrier to the use of carbon dioxide capture technologies is the operating energy requirement, the chief contributor being the energy required to regenerate the capture media. When paired with electricity generation, the parasitic energy load can prohibit implementation. While metal organic frameworks (MOFs) harbor significant adsorption capacities, their thermally insulating nature will require significant energy and time to regenerate. Here, we report a MOF nanocomposite that can be regenerated at high speed and low energy cost. An adsorption system is tailored to deliver a very low energy cost of only 1.29 MJ kg⁻¹_CO2, 45% below commercially deployed materials, which can be exploited to deliver a productivity as high as 3.13 kg_CO2 h⁻¹ kg_Ads⁻¹. The combination of a MOF (Mg-MOF-74) with high adsorption capacity, a magnetic nanoparticle (MgFe₂O₄), and a porous hydrophobic polymer results in a composite that can be used in the magnetic induction swing adsorption (MISA) process.

使用二氧化碳捕集技术的主要障碍是工作能量需求，主要的贡献是再生捕集介质所需的能量。当与发电配对时，寄生能量负载会禁止实施。尽管金属有机骨架（MOF）具有显着的吸附能力，但其绝热性质将需要大量的能量和时间才能再生。在这里，我们报告了可以高速，低能耗地再生的MOF纳米复合材料。的吸附系统被定制以提供仅1.29 MJ公斤的非常低的能量成本^-1 _CO2，45％以下商业部署材料，其可以被利用来作为高递送生产率3.13千克_CO2 ħ ^-1千克_广告^-1。具有高吸附能力的MOF（Mg-MOF-74），磁性纳米颗粒（MgFe ₂ O ₄）和多孔疏水聚合物的组合可形成可用于磁感应摆动吸附（MISA）过程的复合材料。
