Title (EN) METHOD FOR THE PRODUCTION OF AN ELECTRODE CATALYST
(FR) PROCÉDÉ POUR LA FABRICATION D'UN CATALYSEUR D'ÉLECTRODE
(JA) 電極触媒の製造方法
Abstract:
(EN) Provided is a method for the production, by means of the conjoint use of a wet process and a dry process, of an electrode catalyst whereby the effective surface area of the catalyst metal can be increased and a high catalyst metal loading can be achieved. The method comprises a first process (wet process) wherein a carrier (C) such as carbon and catalyst material or catalyst material precursor (S1') are dispersed in a solvent (Y), stirred, and an electrode catalyst intermediate (T1) where catalyst material (S1) is attached to the surface of the carrier (C) is obtained, and a second process (dry process) wherein more catalyst material (S2) is attached to the surface of the intermediate (T1) under dry conditions and catalyst-loaded carrier particles (T2) are formed.
(FR) L'invention porte sur un procédé pour la fabrication, au moyen de l'utilisation conjointe d'un traitement par voie humide et d'un traitement par voie sèche, d'un catalyseur d'électrode, ce par quoi l'aire de surface efficace du métal catalyseur peut être augmentée et un chargement de métal catalyseur élevé peut être obtenu. Le procédé comporte un premier traitement (traitement par voie humide), un support (C) tel que du carbone et un matériau de catalyseur ou un précurseur de matériau de catalyseur (S1') étant dispersés dans un solvant (Y),  agités, et un intermédiaire de catalyseur d'électrode (T1) dans lequel un matériau de catalyseur (S1) est lié à la surface du support (C) étant obtenu, et un second traitement (traitement par voie sèche), plus de matériau de catalyseur (S2) étant lié à la surface de l'intermédiaire (T1) dans des conditions par voie sèche et des particules de support chargées de catalyseur (T2) étant formées.
(JA)  ウェットプロセスとドライプロセスを併用することにより、触媒金属の有効面積を大きくでき、しかも触媒金属の高担持を実現することのできる電極触媒の製造方法を提供する。  溶媒Y中に、カーボン等の担体Cと、触媒物質もしくは触媒物質前駆体S1’と、を分散させ、攪拌して、担体C表面に触媒物質S1が付着してなる電極触媒の中間体T1を生成する第1の工程(ウェットプロセス)と、この中間体T1の表面に、ドライ条件下にて触媒物質S2をさらに付着させて触媒担持担体粒子T2を生成する第2の工程(ドライプロセス)と、からなる電極触媒の製造方法である。
