Here, we report preparation of microporous carbon fibers through carbonization of an Al-based porous coordination polymer (Al-PCP) with furfuryl alcohol (FA) at 1000 degrees C under an inert gas atmosphere. During the carbonization process, the Al species are aggregated to form gamma-alumina nanoparticles. After the carbonization, the gamma-alumina nanoparticles (from 2 to 10 nm) are distributed over the entire area. By chemical treatment with HF, the gamma-alumina nanoparticles can be easily removed to obtain pure microporous carbon. Interestingly, the fibrous morphology of the original Al-PCP is successfully retained after the The effect of the loading amount of FA into the porous networks of Al-PCP on properties of the obtained microporous carbon is carefully examined. From the N-2 adsorption-desorption isotherms, an increase in the BET surface area upon increasing the loading amount of FA is observed. The maximum surface area and pore volume of the obtained microporous carbon reach 513 m(2)/g and 0.844 cc/g, respectively.
