Title (EN) CORE-SHELL CATALYST AND REACTION ACCELERATION METHOD
(FR) CATALYSEUR ÂME-GAINE ET PROCÉDÉ D'ACCÉLÉRATION DE RÉACTION
(JA) コアシェル触媒および反応促進方法
Abstract:
(EN) Provided are: a catalyst having a core-shell structure indicating high activity in an oxygen reduction reaction which is a cathode reaction of a fuel cell; and a reaction acceleration method using the catalyst. This core-shell catalyst which accelerates an oxygen reduction reaction includes silver or palladium as a core material, and platinum as a shell material. The core-shell catalyst has a face-centered cubic lattice (110) surface in the surface of the catalyst.
(FR) L'invention concerne : un catalyseur ayant une structure âme-gaine indiquant une activité élevée dans une réaction de réduction d'oxygène qui est une réaction de cathode d'une pile à combustible ; et un procédé d'accélération de réaction utilisant le catalyseur. Ce catalyseur âme-gaine qui accélère une réaction de réduction d'oxygène comprend de l'argent ou du palladium comme matériau d'âme, et le platine comme matériau de gaine. Le catalyseur âme-gaine a une surface de treillis cubique à faces centrées (110) dans la surface du catalyseur.
(JA) 燃料電池のカソード反応である酸素還元反応において高い活性を示すコアシェル構造を有する触媒、および、当該触媒を用いた反応促進方法を提供する。銀またはパラジウムをコア材料とし、白金をシェル材料とした酸素還元反応を促進するコアシェル触媒であって、触媒表面に面心立方格子の(110)面を有する。
