Perspectives in Adsorptive and Catalytic Mitigations of NOx Using Metal–Organic Frameworks

Because of its high polluting effect, a growing research interest in NO x monitoring, removal, and control has been noticed in the last years. Motivated by the high degree of functional and structural tunability of metal–organic frameworks (MOFs), researchers explored potential MOF-based adsorbents, sensors, and catalysts for NO x mitigation/control. However, this area of research is still in its infancy. In addition, the physical–chemical properties of NO x make this task extremely challenging as some materials suffer relatively weak thermal and/or chemical stability. Nevertheless, some recent encouraging studies have demonstrated superior stability properties that enable MOFs to be considered as alternative benchmark materials for the capture and conversion of NO x . This review offers an overview on the recent progress made in this field and provides some interesting routes on the uses of MOFs for selective NO x adsorption, release, and/or catalytic conversion (via selective catalytic reduction or photocatalysis).
