Carbon-based material, electrode provided with same, and microbial fuel cell

Abstract

A carbon-based material includes an expanded graphite sheet including expanded graphite grains. The carbon-based material also includes nonmetal atoms or nonmetal ions of a nonmetallic element of either nitrogen or sulfur, and surfaces of the expanded graphite grains are doped with the nonmetal atoms or the nonmetal ions. The carbon-based material also includes metal atoms or metal ions of at least one metallic element selected from the element group of group 8 to group 11 of the periodic table, and the surfaces of the expanded graphite grains are doped with the metal atoms or the metal ions. An electrode includes the carbon-based material, and a microbial fuel cell includes the electrode.
