Magnesium oxide/hydroxide was deposited on pitch-based activated carbon fibers which were previously oxidized in air at different temperatures, and the changes in carbon oxidation activity, microporosity, and CH4 adsorptivity of the parent carbons due to Mg deposition were examined. DTA results, chemical analysis, and DRIFT spectra indicate that Mg species are mainly supported on the -COOH groups of the parent carbons, which serve as the catalysts to improve the oxidation activity of carbon.
