Abstract

Activated carbon filaments of diameter ∼ 0.1 μm, mean pore size (BJH) 65 Å, specific surface area 1540 m2/g and burn-off 64% (yield 36%) were obtained by activating carbon filaments of diameter ∼ 0.1 μm in CO2 + N2 (1:1) at 970°C for 100 min. Prior to this activation, the filaments were surface oxidized by exposure to ozone (0.3 vol.% in air) at 150°C for 3 min.
