Abstract
- Industrial air pollutants have serious harmful effects on human health, as industry exhaust is among the main sources of air pollutants, particularly in developing countries. Thus, in this work, a novel material, oxidized poly(arylene sulfide sulfone)/UiO-66-NH2(OPASS/UiO-66-NH2) nanofibrous membrane, was developed for the removal of both volatile organic compounds (VOCs) and PM2.5via electrospinning, post-oxidation treatment, and in situ vertical growth. The result of scanning electron microscopy, Fourier transform infrared, X-ray diffraction, and X-ray photoelectron spectroscopy demonstrated that the OPASS/UiO-66-NH2nanofibrous membrane was successfully prepared. In addition, four kinds of OPASS/UiO-66-NH2nanofibrous membranes were systematically investigated to obtain the optimum one, which was treated for 15 min for UiO-66-NH2growth. It is found OPASS/UiO-66-NH2nanofibrous membrane has outstanding comprehensive performance, high filtration efficiency (99.98%), low pressure drop (120 Pa) for PM2.5removal, and high sorption capacity (30.3, 28.7, and 20.3 mg/g) to dichloromethane, toluene, and benzene. More importantly, the OPASS/UiO-66-NH2nanofibrous membrane could endure high temperatures (250 °C) and harsh environments (N-methylpyrrolidone) and still retain a stable morphology and excellent removal performance for PM2.5and VOCs. The outstanding performance of OPASS/UiO-66-NH2nanofibrous membrane shows potential for the application in high-temperature flue gas treatment.
