Abstract

Abstract : Protection from particulate matter (PM10 and PM2.5 ) and microorganisms using MOFs (metal–organic frameworks) and nanoparticles used in filtration has been a major challenge. Abstract : Protection from particulate matter (PM10 and PM2.5 ) and microorganisms using MOFs (metal–organic frameworks) and nanoparticles used in filtration has been a major challenge. In this study, poly(vinylidene fluoride) (PVDF) nanofibers embedded with MOF-801 and Cu2 O nanoparticles were prepared using electrospinning. The modified nanofibers adsorb particulate matter (PM10 and PM2.5 ) and reduce microorganism populations, thereby improving filtration and antibacterial processes. The multifunctional nanomaterials, which are suitable for use in the presence of hazardous concentrations of particulate matter and E. coli because of the well-dispersed MOF-801 and Cu2 O on the nanofibers, show very efficient particulate matter adsorption (PM2.5 : 64.46%, PM10 : 63.19% after 5 min and PM2.5 : 88.26%, PM10 : 85.22% after 10 min, respectively).
