Metal–organic frameworks (MOFs) are the object of intense research targeting their deployment as adsorbents for a wide range of gas separations, such as CO2 capture, biogas upgrading, air separation and small hydrocarbon separation. The scope of this review is to provide chemists, materials scientists and engineers with an overview of the state-of-the-art and of the main challenges in the field of adsorption-based gas separations using MOFs. To do so, we first discuss current gas separation challenges for which adsorption could play a role. The following three sections of the paper describe process-level considerations in the design, selection and deployment of MOFs as sorbents and subsequently focus on material-level considerations. Both the process and the material aspects cover experimental and computational work. Going from the process scale to the atomic scale, we aim to highlight the links and synergies between the two and identify the current barriers that hamper the development of adsorption-based gas separations using MOFs as sorbents. Throughout the article, we also provide fundamental and technical information related to MOF design, synthesis, characterisation and sorption testing.

用于吸附式气体分离的工程金属-有机框架:从过程到原子尺度

金属有机框架 (MOF) 是深入研究的对象,旨在将其部署为广泛的气体分离吸附剂,例如 CO 2捕集、沼气提质、空气分离和小烃分离。本综述的范围是为化学家、材料科学家和工程师提供对使用 MOF 进行基于吸附的气体分离领域的最新技术和主要挑战的概述。为此,我们首先讨论吸附可以发挥作用的当前气体分离挑战。本文的以下三个部分描述了作为吸附剂的 MOF 的设计、选择和部署中的工艺级考虑因素,随后重点关注材料级考虑因素。过程和材料方面都涵盖了实验和计算工作。从过程尺度到原子尺度,我们的目标是强调两者之间的联系和协同作用,并确定当前阻碍使用 MOF 作为吸附剂的基于吸附的气体分离发展的障碍。在整篇文章中,我们还提供了与 MOF 设计、合成、表征和吸附测试相关的基础和技术信息。
