Tailored Gas Adsorption Properties of Electrospun Carbon Nanofibers for Gas Separation and Storage.

ABSTRACT: Carbon nanofibers (CNFs) derived from electrospun polyacrylonitrile (PAN) were investigated with respect to their gas adsorption properties. By employing CO₂ adsorption measurements, it is shown that the adsorption capacity and selectivity of the fibers can be tailored by means of the applied carbonization temperature. General pore properties of the CNFs were identified by Ar adsorption measurements, whereas CO₂ adsorption measurements provided information about the ultramicroporosity, adsorption energies, and adsorption capacities. Ideal adsorbed solution theory (IAST) selectivities under practically relevant conditions were determined by evaluation of single-component data for N₂ and CO₂ . Especially for low carbonization temperatures, the CNFs
