Groundbreaking research over the past 15 years has established metal–organic frameworks (MOFs) as adsorbents capable of unprecedented gas adsorption capacity. This has encouraged the contemplation of their use in applications such as increasing the storage capacity in natural gas fuel tanks, or the capture of carbon dioxide from coal-fired flue gas streams. However, while the gas adsorption capacity of MOFs is large, not all stored gas can be readily released to realize the efficient regeneration of MOF adsorbents. This leads to an increase in energy requirements, or working capacities significantly lower than the amount of gas adsorbed. This requirement for low energy means to efficiently release more stored gas has motivated the research in our group toward the triggered release of the stored gas from MOFs. Using CO₂ as a typical gas adsorbate, we have developed three new methods of releasing stored gas with external stimuli that include light induction swing adsorption, magnetic induction swing adsorption, and their combination, denoted as LISA, MISA and MaLISA, respectively.

由外部刺激触发的金属有机框架中的低能CO ₂释放

在过去的15年中，突破性的研究已经建立了金属有机框架（MOF）作为能够具有前所未有的气体吸附能力的吸附剂。这鼓励了人们考虑将其用于诸如增加天然气燃料罐中的存储容量或从燃煤烟道气中捕获二氧化碳的应用中。然而，尽管MOF的气体吸附能力大，但是并非所有储存的气体都能容易地释放以实现MOF吸附剂的有效再生。这导致能量需求增加，或者工作能力大大低于吸附的气体量。对低能耗的要求意味着要有效释放更多的储气，这促使我们小组的研究朝着从MOFs触发释放储气的方向发展。使用CO ₂ 作为一种典型的气体吸附物，我们开发了三种通过外部刺激释放储存气体的新方法，包括光感应摆幅吸附，磁感应摆幅吸附及其组合，分别表示为LISA，MISA和MaLISA。
