To mitigate carbon emission from the combustion of fossil fuels, membrane is advantageous due to the fact that membrane is a thin interphase acting as a selective barrier separating two phases. This thinness, typically in the range of 100 nm to a few micrometers, provides an almost natural platform to implement functional nanostructures. In this review, the recent progress in nanostructured membrane materials for CO₂ capture will be discussed, including applications in flue gas decarbonizing (CO₂/N₂ separation) and syngas purification (CO₂/H₂ separation). In addition, the fundamentals of membrane technologies are also introduced. The reviewed nanostructure formation is confined to solid state materials, including polymer with intrinsic microporosity, carbon-based membranes, zeolite, and metal organic framework.
为了减轻化石燃料燃烧产生的碳排放，膜具有优势，因为膜是一种作为选择性屏障的薄相间层，将两相分隔开来。这种薄膜的厚度通常在 100nm 到几微米之间，为实现功能纳米结构提供了一个几乎自然的平台。在这篇综述中，将讨论用于 CO₂捕获的纳米结构膜材料的最新进展，包括在烟气脱碳（CO₂/N₂分离）和合成气净化（CO₂/H₂分离）中的应用。此外，还介绍了膜技术的基本原理。综述的纳米结构形成仅限于固态材料，包括具有本征微孔的聚合物、碳基膜、沸石和金属有机骨架。
