Abstract

Catalyseur composé d'or, d'un oxyde de métal de transition avec lequel l'or forme un complexe et d'un oxyde d'étain capturé sur un support d'oxyde composé d'un mélange d'oxyde de cérium et de dioxyde de titane. L'oxyde d'étain est présent en quantité inférieure à 0,4 % en poids du catalyseur. On peut utiliser ce catalyseur, de façon spécifique, pour l'oxydation sélective d'oxyde de carbone dans un mélange d'hydrogène et d'oxyde de carbone.
