Title:
CARBON FOR SUPPORTING CATALYST AND PRODUCTION PROCESS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/208742
Kind Code:
A1
Abstract:
Provided is carbon for supporting catalysts thereon which combines the excellent property of dispersedly supporting catalyst-metal particles with excellent resistance to oxidative degradation. The carbon for supporting catalysts satisfies the following requirements (a) to (d). (a) The carbon surface has a crystallite thickness Lc(002), calculated from the results of an examination by wide-angle X-ray diffractometry, of 2.0 nm or greater. (b) The carbon surface, when examined by Raman spectrometry, gives a spectrum wherein the ratio of the area of a D1-band (1,350 cm-1) peak to the area of a G-band (1,590 cm-1) peak, D/G, is 0.5-2.5. (c) The carbon has pores comprising mesopores, the volume of the mesopores being 0.35-1.3 cm3/g. (d) The ratio of the mesopore volume to the total pore volume is 0.6-1.0.
