摘要： A support for carrying a catalyst is obtained by carbonizing raw materials containing a nitrogen-containing organic substance and a metal. The support for carrying a catalyst may have a peak at a diffraction angle of around 26° in an X-ray diffraction pattern, the peak including 20 to 45% of a graphite-like structure component and 55 to 80% of an amorphous component. In addition, the support for carrying a catalyst may have an intensity ratio of a band at 1,360 cm−1 to a band at 1,580 cm−1 (I1,360/I1,580) in a Raman spectrum of 0.3 or more and 1.0 or less. In addition, the support for carrying a catalyst may be obtained by carbonizing the raw materials to obtain a carbonized material, subjecting the carbonized material to a metal removal treatment, and subjecting the resultant to a heat treatment.
