Method for producing fine catalyst particles and method for producing carbon-supported catalyst: United States Patent

Bilim, Doğa ve Matematik

The present invention is to provide fine catalyst particles with better catalytic performance than ever before and a carbon-supported catalyst with better catalytic performance than ever before. Disclosed is a method for producing fine catalyst particles, comprising: a potential applying step of applying a potential to the fine palladium-containing particles in a first dispersion, until a peak indicating a Pd{111} surface in a reduction wave of a cyclic voltammogram becomes larger than a peak indicating a Pd{110} or Pd{100} surface in the reduction wave of the cyclic voltammogram; a copper covering step of covering at least part of the fine palladium-containing particle with copper by preparing a second dispersion by mixing the first dispersion and a copper-containing solution after the potential applying step, and applying a potential that is nobler than the oxidation-reduction potential of copper to the fine palladium-containing particles in the second dispersion; and a platinum covering step of covering at least part of the fine palladium-containing particle with platinum by mixing the second dispersion and a platinum-containing solution after the copper covering step.
