Title:
METHOD FOR PRODUCING ELECTRODE CATALYST, AND ELECTRODE CATALYST
Document Type and Number:
WIPO Patent Application WO2010110469
Kind Code:
A1
Abstract:
Disclosed is a method for producing an electrode catalyst, which comprises a step wherein a precursor of the electrode catalyst is fired under the conditions where the second material specified below is changed into a carbon material. The precursor of the electrode catalyst is obtained by hydrothermally reacting a mixture that contains the first material specified below and the second material specified below in the presence of water that is in a supercritical state or in a subcritical state, or alternatively obtained by mixing the second material specified below with a reaction product that is obtained by hydrothermally reacting the first material specified below in the presence of water that is in a supercritical state or in a subcritical state. First material: a metal compound that is configured from one or more metal elements selected from the group consisting of group 4A elements and group 5A elements, and one or more non-metal elements selected from the group consisting of hydrogen, nitrogen, chlorine, carbon, boron, sulfur and oxygen Second material: a precursor of a carbon material
