The webs of 400 ± 100 nm fiber were prepared by electrospinning of PAN and zeolite blend. The webs were stabilized at 280℃ in the air atmosphere, carbonized and activated at 1000℃ in the nitrogen with 30 vol. % steam. The prepared activated carbon nanofibers (ACFs) of average diameter were 300 ± 50 nm. The average pore diameter and specific surface areas were 0.6~0.7 nm. The surface of cabon nanofibers was characterized by FE-SEM (scanning electron microscopy), thermal stabilities by TGA (thermo gravimetric analysis) and pore characteristic by BET and chemical characteristic of cabon nanofiber surface by XPS (x-ray photoelectron spectroscopy). The condition of the gas were 200ppm CO2 in He balance. The Adsorption amount of carbon dioxide were increased by an addition of zeolite. |
