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 exhibit very good low‐pressure adsorption performance
and excellent CO2/N2 IAST selectivities of 350 at 20 mbar
and 132 at 1 bar, which are attributed to a
molecular‐sieve effect in very narrow slit pores. These
IAST selectivities are some of the highest values for carbon
materials reported in the literature so far and the highest
IAST selectivities for as‐prepared, non‐post‐treated
carbon ever.},
