GOPAN Electrospun Nanofiber Filters for NO₂ Removal
View through CrossRef
Indoor air quality (IAQ) can be negatively affected by outdoor pollutants. Among them, traffic-related NO₂ emissions have adverse health effects on humans. The present study investigated the NO₂ removal by novel composite GOPAN nanofiber filters composed of graphene oxide (GO) and polyacrylonitrile (PAN) polymer fabricated via electrospinning. GOPAN nanofibers were generated with varying GO concentrations (0.5-3% wt.) to evaluate the effect of the GO content on NO₂ removal efficiency indoors. Among all GOPAN nanofibers, the 2% wt. GO-doped nanofiber filter (2GOPAN) achieved ca. 31% NO₂ removal efficiency. The findings indicate that the amount of GO in the GOPAN electrospun nanofiber fibers affects the performance of the filter with respect to the NO₂ removal.
