Title:
CARBON CATALYST, PROCESS FOR PRODUCTION OF SAME, AND ELECTRODE AND BATTERY EACH UTILIZING SAME
Document Type and Number:
WIPO Patent Application WO/2011/055739
Kind Code:
A1
Abstract:
Disclosed is a carbon catalyst having an improved activity.
The carbon catalyst is produced by (S1) carbonizing a raw material comprising an organic compound that acts as a carbon source, a metal and an electrically conductive carbon material to produce a carbonized material, (S2) impregnating the carbonized material with a metal, and (S3) heating the resulting product.
