Abstract
The present invention provides a method for producing a nitrogen-doped highly graphitic porous carbon body, and a nitrogen-doped highly graphitic porous carbon body produced according to the same. Also, the present invention provides a method for producing a sulfur and nitrogen double-doped highly graphitic porous carbon body, a sulfur and nitrogen double-doped highly graphitic porous carbon body produced according to the same, and an electrode catalyst for a fuel cell and/or a water electrolysis reaction comprising the carbon body.
Claims9
A nitrogen-doped highly graphitic porous carbon body which contains 0.5 to 6 atom % of N as a heteroelement, and has a peak intensity ratio ID/IG of less than 1.0 as measured with a Raman spectrum (ID is a peak intensity of a D band (at around 1,350 cm−1), and IG is a peak intensity of a G band (at around 1,580 cm−1) in the Raman spectrum), wherein the peak intensity ratio I2D/IG is 0.5 or more as measured with the Raman spectrum of the nitrogen-doped highly graphitic porous carbon body, wherein I2D is a peak intensity of a 2D band at around 2,700 cm−1 in the Raman spectrum.
