Extremely large mesoporous carbon fibers synthesized by the addition of rare earth metal complexes and their unique adsorption behaviors

Extremely highly mesoporous activated carbon fibers (see Figure) have been synthesized for the first time from pitch fibers containing rare earth metal complexes. These fibers have potential applications in the purification of drinking water, for example, owing to their ability to absorb giant molecules such as humic acid. Investigations of the absorption behavior of the fibers are reported. fig.magnified image
