16 Claims

1. A metal-supported catalyst, comprising:

a carbon carrier; and

catalyst metal particles each containing a noble metal supported on the carbon carrier,

wherein a volume of first pores each having a diameter of 0.5 nm or more and 2.0 nm or less per unit weight of the carbon carrier is 0.20 (cm³/g-carrier) or more,

wherein a volume of second pores each having a diameter of more than 2.0 nm and 4.0 nm or less per unit weight of the carbon carrier is 0.20 (cm³/g-carrier) or more, and

wherein a ratio of a content (wt %) of the noble metal measured by X-ray photoelectron spectroscopy to a content (wt %) of the noble metal measured by inductively coupled plasma mass spectrometry is 0.35 or more and 0.75 or less.
