Abstract

Surface carboxylic groups of oxidized polymer-pyrolized active carbons were converted to surface amides, azides, and nitriles by means of reactions used for transformations of functional groups in organic chemistry. Further reduction of N-containing groups took different courses, resulting in either amine or hydroxylic groups depending on the starting material. Comparing adsorption data of methylene blue, probable mechanisms of surface reactions, and porous structure of the carbons it has been concluded that the phenomenon described is due to the difference in the rate of reagent transport to the surface which, in its turn depends on the porous structure of active carbon.
