Removal of particulate matter with metal–organic framework-incorporated materials

Recently, the contamination of air, both indoors and outdoors, has been severe, especially due to particulate matter (PM) in some cities and countries like India, China, and Korea. Therefore, both preventing the evolution of PM and removing PM from air are highly important for sustainability. In this review, progress regarding PM (especially 2.5 µm or less) removal via filtration is summarized. In particular, air filters modified or composed with metal–organic frameworks (MOFs) or MOF-related materials are discussed, including preparation methods. Moreover, improved performances with the incorporation of MOFs and mechanisms to explain the observations are discussed. Finally, perspectives in the field for effective PM capture/removal with MOF-incorporated filters are suggested after a brief summary of the researches.
