Abstract
A catalyst carrier production process 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.
