Abstract
A method for producing catalyst particles, which are for an electrochemical reaction and in which catalytic noble metal particles are carried on conductive oxide particles, includes: using metal atom-containing organic compounds as a precursor of the conductive oxide particles and a precursor of the catalytic noble metal particles, and dissolving the metal atom-containing organic compounds in an organic solvent to obtain a precursor solution; and spraying and combusting the precursor solution.

A method for producing catalyst particles for electrochemical reaction that comprise noble metal catalyst particles supported on conductive oxide particles, the method including:
- using metal atom-containing organic compounds as both a precursor for the conductive oxide particles and a precursor for the noble metal catalyst particles, dissolving them in an organic solvent to obtain a precursor solution, and
- spraying the precursor solution and burning it.
Catalyst particles for electrochemical reaction, comprising noble metal catalyst particles supported on conductive oxide particles,
- wherein in measurement by cyclic voltammetry (CV) under a nitrogen atmosphere using an electrode comprising catalyst particles as the working electrode, a reversible hydrogen electrode (RHE) as the reference electrode, and a Pt wire electrode as the counter electrode,
- a peak is observed near 0.4 V (vs.RHE) when sweeping in the direction of increasing potential and the direction of decreasing potential.
