Abstract
(EN) [Problem] To provide a gold-supported carbon catalyst in which the size of gold fine particles is reduced and the strength of adhesion thereof to carbon black is increased, and aggregation of gold fine particles can be suppressed. [Solution] A gold-supported carbon catalyst in which alkanethiol is coordinated with a coverage factor of 10-70%, and gold fine particles having an average particle diameter of 1.0-1.5 nm are supported on carbon black.
(FR) Le problème décrit par la présente invention est de fournir un catalyseur carboné supporté par de l'or dans lequel la taille de particules fines d'or est réduite et la force d'adhésion de celles-ci au noir de carbone est augmentée, et l'agrégation de particules fines d'or peut être supprimée. La solution selon l'invention porte sur un catalyseur carboné supporté par de l'or dans lequel un alcanéthiol est coordonné avec un facteur de couverture de 10 à 70 %, et des particules fines d'or ayant un diamètre moyen de particule de 1,0 à 1,5 nm sont supportées sur du noir de carbone.
(JA) 【課題】金微粒子サイズがより小さく、且つカーボンブラックとの密着強度が強く、金微粒子の凝集を抑制できる金担持カーボン触媒を提供する。 【解決手段】アルカンチオールが被覆率10～70％で配位し、平均粒径1.0～1.5nmの金微粒子をカーボンブラックに担持した金担持カーボン触媒。
