The quest for advanced designer adsorbents for air filtration and monitoring hazardous trace gases has recently been more and more driven by the need to ensure clean air in indoor, outdoor, and industrial environments. How to increase safety with regard to personal protection in the event of hazardous gas exposure is a critical question for an ever‐growing population spending most of their lifetime indoors, but is also crucial for the chemical industry in order to protect future generations of employees from potential hazards. Metal–organic frameworks (MOFs) are already quite advanced and promising in terms of capacity and specific affinity to overcome limitations of current adsorbent materials for trace and toxic gas adsorption. Due to their advantageous features (e.g., high specific surface area, catalytic activity, tailorable pore sizes, structural diversity, and range of chemical and physical properties), MOFs offer a high potential as adsorbents for air filtration and monitoring of hazardous trace gases. Three advanced topics are considered here, in applying MOFs for selective adsorption: (i) toxic gas adsorption toward filtration for respiratory protection as well as indoor and cabin air, (ii) enrichment of hazardous gases using MOFs, and (iii) MOFs as sensors for toxic trace gases and explosives.

金属有机框架对有害微量气体的吸附和检测

最近，对确保室内，室外和工业环境中的清洁空气的需求越来越多地推动了对用于空气过滤和监测有害痕量气体的高级设计吸附剂的追求。对于不断增长的人口将大部分一生都花在室内的问题，如何在危险气体暴露的情况下提高人身保护的安全性是一个关键问题，但对于化学工业来说，也至关重要，以保护后代的员工免受伤害。潜在危险。金属有机骨架（MOF）已经非常先进，并且在克服目前吸附材料对痕量和有毒气体吸附的限制方面的能力和特定亲和力方面很有前途。由于它们的优势（例如，高比表面积，催化活性，可定制的孔径，结构多样性以及化学和物理性质的范围），MOF具有很高的潜力，可以用作空气过滤和危险痕量气体监测的吸附剂。在将MOF应用于选择性吸附时，这里考虑了三个高级主题：（i）有毒气体吸附朝着呼吸保护以及室内和车厢空气过滤的过滤；（ii）使用MOF富集有害气体，以及（iii）MOF作为传感器用于有毒微量气体和爆炸物。
