Title:
コアシェル触媒および反応促進方法
Document Type and Number:
Japanese Patent JP6805435
Kind Code:
B2
Abstract:
Provided are (i) a catalyst that has a core-shell structure and is highly active in an oxygen reduction reaction, which is a cathode reaction of a fuel cell, and (ii) a reaction acceleration method in which the catalyst is used. A core-shell catalyst for accelerating an oxygen reduction reaction, contains: silver or palladium as a core material; and platinum as a shell material, the core-shell catalyst having, on a surface thereof, a (110) surface of a face centered cubic lattice.
