摘要
Method for producing a substrate with Au (gold) nanoclusters affixed to the surface thereof and substrate and catalyst obtained by means of said method. The method consists in preparing a solution containing, in disperse form, Au nanoclusters and, also in disperse form, a substrate with a surface functionalized with a polyelectrolyte that confers a net electric charge thereon, and in intensely agitating said solution to affix Au nanoclusters to the substrate surface. This results in a substrate that has a surface with Au nanoclusters affixed in disperse form, significantly without clusters. The invention also relates to a catalyst that comprises said substrate with Au nanoclusters affixed to the surface thereof. Said catalyst is particularly suitable for use in oxidation reactions.
