Title:

SULFONATED AMORPHOUS CARBON, PROCESS FOR PRODUCING THE SAME AND USE THEREOF

Document Type and Number:

WIPO Patent Application WO/2005/029508

Kind Code:

A1

Abstract:

A sulfonated amorphous carbon characterized in that chemical shifts of sulfonated condensed aromatic carbon 6-membered ring and condensed aromatic carbon 6-membered ring are detected in a ¹³C nuclear magnetic resonance spectrum and at least diffraction peak of carbon (002) face whose half-value width (2Ѳ) is in the range of 5 to 30° detected in powder X-ray diffractometry, the sulfonated amorphous carbon exhibiting 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.
