Abstract
Official abstract text for this publication.
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 (I 1,360 /I 1,580 ) 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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A support for carrying a catalyst, comprising a carbonized material containing nitrogen atoms and a metal, wherein the support has a catalyst-supporting performance such that when the support is loaded with 10 wt % of a platinum catalyst with respect to the support, the platinum catalyst is retained on the support in a proportion of at least 6.7 wt % and not more than 10 wt % with respect to the support after subjecting the support to the refluxing, wa…
