Claim:
1. A process for producing a composite catalyst comprising: a step (a) of mixing a transition metal compound (1), a nitrogen-containing organic compound (2) and a solvent to provide a thermally treated product precursor solution; a step (b) of removing the solvent from the thermally treated product precursor solution; 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 thermally treated product; and a step (d) of providing a composite catalyst comprising the thermally treated product and a catalyst metal supported on the thermally treated product; wherein the transition metal compound (1) is partly or wholly a compound comprising a transition metal element (M1) selected from the group 4 and 5 elements of the periodic table as a transition metal element; one or both of the transition metal compound (1) and the nitrogen-containing organic compound (2) comprises an oxygen atom; and the catalyst metal is at least one selected from the group consisting of platinum, gold, silver, copper, palladium, rhodium, ruthenium, iridium, osmium, rhenium and an alloy made of two or more thereof.
