Abstract

Perfluorocarbons (PFCs) such as CF₄, C₂F_6, and C₃F₈, are extensively used in the microelectronics and semiconductor industries, yet their global warming potentials—thousands of times greater than that of CO₂—underscore the urgent need for effective mitigation strategies. While converting PFCs into non-PFCs offers a method for their destruction, a more sustainable approach lies in the recovery and recycling of these compounds using advanced adsorbents. This review explores the potential of cutting-edge porous materials, including metal-organic frameworks (MOFs), covalent-organic frameworks (COFs), and porous organic cages (POCs), for the adsorption and separation of PFCs. By precisely tuning pore sizes and chemical environments through modifications of metal ions and ligands, these porous adsorbents can be tailored to exhibit specific adsorption and separation capabilities. The review focuses on the selective separation of PFCs from nitrogen and other fluorinated gases, with particular emphasis on the latest advancements in adsorbents designed to differentiate between PFCs and other fluorinated compounds in the presence of nitrogen.

用于全氟化碳温室气体吸附和分离的多孔吸附剂的研究进展

CF4、C2F6 和 C3F8 等全氟化碳（PFCs）被广泛应用于微电子和半导体行业，但它们的全球升温潜能值是 CO₂ 的数千倍，因此迫切需要有效的减缓战略。将全氟化合物转化为非全氟化合物是一种销毁全氟化合物的方法，而更可持续的方法则是利用先进的吸附剂回收和循环利用这些化合物。本综述探讨了尖端多孔材料（包括金属有机框架 (MOF)、共价有机框架 (COF) 和多孔有机笼 (POC)）在吸附和分离 PFCs 方面的潜力。通过对金属离子和配体的改性来精确调整孔隙大小和化学环境，这些多孔吸附剂可以量身定制，从而展现出特定的吸附和分离能力。本综述侧重于从氮气和其他含氟气体中选择性分离全氟化合物，特别强调了吸附剂的最新进展，这些吸附剂旨在区分氮气中的全氟化合物和其他含氟化合物。
