The present invention is intended to reduce the amount of use of platinum or the like and to improve corrosion resistance. Objects of the invention are to provide a catalyst carrier production process that can reduce the amount of a catalyst metal used in an electrode catalyst while maintaining high performance by enhancing the activity of the supported catalyst metal, thereby achieving electrode catalyst cost reduction, a catalyst that can have high performance despite a low catalyst metal content, and a process for producing the catalyst. The catalyst carrier production process according to the invention includes a step (a) of mixing a transition metal compound (1), a nitrogen-containing organic compound (2), and a solvent to provide a catalyst carrier precursor solution; a step (b) of removing the solvent from the catalyst carrier precursor solution; and a step (c) of thermally treating a solid residue obtained in the step (b) at a temperature of 500 to 1100°C to provide a catalyst carrier; wherein the transition metal compound (1) is partly or wholly a compound including a transition metal element (M1) selected from the group 4 and 5 elements of the periodic table as a transition metal element; and at least one of the transition metal compound (1) and the nitrogen-containing organic compound (2) includes an oxygen atom. |
