Membrane and membrane process have been widely considered as one of the best candidates for mitigating CO₂ emissions from the combustion or utilization of fossil fuels. Various amine‐containing polymers constitute an important class of membranes, where the highly selective CO₂ transport is achieved by the facilitated transport mechanism. In this review, the amine–CO₂ chemistry is discussed in conjunction with the mechanism of the reaction‐mediated CO₂ transport. A wide variety of amine‐containing polymers are discussed based on two synthesis motifs: (a) polyamines with amino groups covalently bound to the polymer backbone and (b) small molecule amines embedded in a polymer matrix. This review concludes with the remarks on the facilitated transport membranes for post‐combustion carbon capture (CO₂/N₂) and hydrogen purification (CO₂/H₂).

聚合物促进传输膜用于二氧化碳分离和氢气纯化的最新进展

膜和膜工艺已被广泛认为是减轻化石燃料燃烧或利用引起的CO ₂排放的最佳候选人之一。各种含胺聚合物构成一类重要的膜，其中通过促进的传输机制实现了高度选择性的CO ₂传输。在这篇综述中，结合反应介导的CO ₂的机理讨论了胺-CO _2的化学反应。运输。基于两个合成基序，讨论了多种含胺聚合物：（a）具有共价键结合到聚合物主链上的氨基的多胺和（b）嵌入聚合物基质中的小分子胺。本文以在燃烧后捕集碳（CO ₂ / N ₂）和氢纯化（CO ₂ / H ₂）的运输膜上的评论作为结束。
