The extra CO2 that has already been released into the atmosphere has to be removed in order to create a carbon–neutral world. Technologies have been created to remove carbon dioxide from wet flue gas or even directly from ambient air; however, these technologies have not been widely deployed yet. New generations of CO2 sorbents have been produced as a consequence of recent improvements in material assembly and surface chemistry. We summarize recent progress on water-stable and encapsulated metal–organic frameworks (MOFs) for CO2 capture under a wide range of environmental and operating conditions. In particular, newly developed water-stable MOFs and hydrophobic coating technologies are discussed with insights into their materials discovery and the synergistic effects between different components of these hybrid sorbent systems. The future perspectives and directions of water-stable and encapsulated MOFs are also elucidated for Direct Air Capture of CO2 and CO2 capture from wet flue gas.

用于从环境空气和湿烟道气中捕获 CO2 的水稳性 MOF 和疏水封装 MOF

为了创造一个碳中和的世界,必须去除已经释放到大气中的额外 CO 2 。已经开发出从湿烟气中甚至直接从环境空气中去除二氧化碳的技术;然而,这些技术尚未得到广泛部署。由于最近材料组装和表面化学方面的改进,已经生产出新一代 CO 2吸附剂。我们总结了用于在各种环境和操作条件下捕获CO 2的水稳定和封装金属有机框架 (MOF) 的最新进展。特别是新开发的水稳性 MOF 和疏水涂层技术讨论了他们的材料发现和这些混合吸附剂系统不同组件之间的协同效应的见解。还阐明了水稳定和封装 MOF 的未来前景和方向,用于直接空气捕获 CO 2和从湿烟道气中捕获CO 2 。
