Abstract

An amorphous carbon having sulfonate group introduced therein is provided which is characterized in that chemical shifts of a condensed aromatic carbon 6-membered ring and a condensed aromatic carbon 6-membered ring having sulfonate group bonded thereto are detected in aC nuclear magnetic resonance spectrum and that at least a diffraction peak of carbon (002) face whose half-value width (2θ) is in the range of 5 to 30° is detected in powder X-ray diffractometry, and which exhibits proton conductivity. This sulfonated amorphous carbon is very useful as a proton conductor material or solid acid catalyst because it excels in proton conductivity, acid catalytic activity, thermal stability and chemical stability and can be produced at low cost.
