Abstract:
To provide catalyst particles that can exhibit high activity. Catalyst particles, which are alloy particles formed from platinum atoms and non-platinum metal atoms, each alloy particle having a main body that constitutes a granular form; and a plurality of protrusions protruding outward from the outer surface of the main body, in which the main body is formed from a non-platinum metal and platinum, the protrusions are formed from platinum as a main component, and the aspect ratio (diameter/length) of the protrusions is higher than 0 and lower than or equal to 2.

Claim (Index 17):
A method for producing the catalyst particles according to  claim 9 , the method comprising:\n preparing a non-platinum metal precursor solution including a non-platinum metal precursor (Step (1)); preparing a reducing agent mixed liquid including an adsorbent and a reducing agent (Step (2)); mixing the non-platinum metal precursor solution with the reducing agent mixed liquid, reducing the non-platinum metal precursor, and thereby obtaining a non-platinum metal particle dispersion liquid (Step (3)); preparing a platinum precursor solution including a platinum precursor (Step (4)); and mixing the non-platinum metal particle dispersion liquid with the platinum precursor solution, reducing the platinum precursor, and thereby growing platinum on the non-platinum metal particle surface to form protrusions (Step (5)), wherein in Step (3), the amount of addition of the adsorbent in the reducing agent mixed liquid is 2.3 mol or more with respect to 1 mol (in terms of metal) of the non-platinum metal precursor.
