Developing nanofiber membrane materials with dual functionality for VOCs and particulate matter removal Available to Purchase

Particulate matter and volatile organic compounds (VOCs) represent significant sources of indoor and outdoor air pollution, posing major health risks. Nanofiber membranes, known for their robust strength, extensive specific surface area, and flexibility, have found widespread use in filtration applications. In this study, Pt/Co₃O₄-CeO₂@PI nanofiber filters with catalytic properties were successfully fabricated using electrospinning, wet impregnation, and thermal treatment techniques. Tests conducted at room temperature demonstrated the filters’ effectiveness in treating particulate matter and removing VOCs. Notably, the filter containing 0.1 wt% Co₃O₄-CeO₂@PI exhibited the highest removal efficiency, achieving 88.2% formaldehyde removal and 87.17% toluene removal. After multiple cycles, both removal rates remained above 75%. Furthermore, the filter showed impressive performance in PM0.3 filtration, achieving an efficiency of 98.13% at elevated temperatures. These findings underscore the promising potential of Pt/Co₃O₄-CeO₂@PI nanofiber filters for air purification applications
