L'objectif de notre travail était la préparation contrôlée des nanoparticules d'or stabilisée par argile et PVA et supportés sur oxydes à base de cérine pour des applications dans le domaine de la catalyse hétérogène. Une nouvelle méthode de préparation a été mise au point. Elle permet de diminuer le nombre des paramètres à contrôler afin...

The influence of the protecting agent's nature on gold particle size and dispersion was studied in this work over a series of gold-based catalysts. CO and glucose oxidation were chosen as catalytic reactions to determine the catalyst's structure–activity relationship. The nature of the support appeared to be the predominant factor for the...

A series of gold colloids were prepared and immobilized on commercial activated carbon. The influence of the colloid preparation and stability were studied and related to the gold particle size in the final catalyst. The catalysts show an important activity in the glucose to gluconic acid oxidation reaction, leading to gluconic acid yield close...
