Pd particles for catalyst and Pd powder for catalyst, method for producing Pd particles for catalyst

摘要

The Pd particles for catalyst (1) have a spherical core (2) containing Ni and P and a Pd plating layer (3) covering the surface of the core (2), and the Pd plating layer And is formed into a film shape. The Pd powder for catalyst is a powder containing Pd particles for catalyst (1), the median diameter d50 in the cumulative volume distribution curve is 5 m or more and 100 m or less, and [(d 90-d 10) / d 50] 0.8.
