Abstract:
The present invention is to provide a carbon powder that can provide a catalyst having excellent durability and a catalyst. A carbon powder for catalyst of the present invention is a carbon powder containing as a main component carbon, which has a BET specific surface area per unit weight of 900 m2/g or greater, and a ratio R′ (D′/G intensity ratio) of peak intensity for a D′-band (D′ intensity) measured in the vicinity of 1620 cm−1 to peak intensity for a G-band (G intensity) measured in the vicinity of 1580 cm−1 by Raman spectroscopy of 0.6 or less.
