| abstract | (57) [Summary] [PROBLEMS] To further improve the heat resistance and stably provide the high heat resistance to stabilize the quality. After carrying a catalyst metal on a porous carrier, the catalyst is heat-treated in a non-oxidizing atmosphere to reduce the specific surface area at a reduction rate of 30 to 70%. By performing the heat treatment so that the specific surface area reduction rate falls within this range, the degree of shrinkage of the pores in the support becomes an optimal range, and the supported catalyst metal is tightly surrounded by the support. Therefore, the movement of the supported catalyst metal is regulated, and sintering of the catalyst metal in a high temperature range is suppressed. |
