Preparation of Co₃O₄-Activated Carbon Fiber by Electrospinning and its Performance of Adsorbing Low Concentration SO₂

Abstract:

The poly (vinyl pyrrolidone) (PVP)/Cobalt Acetate Composite nanofibers were prepared by electrospinning method. Then we got Co₃O₄-activated carbon fiber (ACF) from PVP/Cobalt Acetate composite nanofibers after preoxidation, carbonation and activation. Study the effect of different adsorption conditions on the adsorption rate of low concentration SO₂. The SEM, TG-DTA, XRD, FT-IR and BET analysis methods is used to characterize. The results show that the specific surface area of Co₃O₄-ACF obtained reach 1238.5 m²/g, and it contains Co₃O₄ after carbonation. The adsorption rate can reach 69.0%, when the concentration of SO₂ is 1.0 μg/mL, adsorption temperature is 20, and adsorption time is 10 minimum.
