| 摘要 |
A method for producing an electrode catalyst, comprising a step of calcining a precursor of the electrode catalyst under conditions under which a second material defined below can change into a carbonaceous material, the precursor having been obtained by continuously hydrothermally reacting a mixture containing a first material defined below and the second material defined below in the presence of supercritical or subcritical water, wherein the first material is defined to be a metal compound composed of one or more metal elements selected from the group consisting of the elements of Group 4A and the elements of Group 5A group and one or more non-metal elements selected from the group consisting of hydrogen, nitrogen, chlorine, carbon, boron, sulfur, and oxygen, and the second material is defined to be a precursor of a carbonaceous material.
