El repte/The challenge
Developing processes to obtain compositions comprising Au nanoclusters, which have shown extraordinary catalytic properties, has become a main goal due to its large range of applications in research but also in industry. An important hardship for obtaining of such compositions is to prevent Au nanoclusters from aggregation, which are notably less reactive and efficient. Disparate methods have been proposed to avoid nanocluster aggregations by now without significant success, either due to the alteration of the physicochemical properties of the nanoclusters, leading to a devaluation in their catalytic capacity, or because it is too complex to carry out these procedures in industrial processes. Therefore, there is a need to develop a procedure to obtain a composition of Au nanoclusters this being stable, efficient and applicable on an industrial scale.
La tecnologia/The technology
The invention refers to a substrate with Au nanoclusters attached in its surface. Nanoclusters are attached to the surface through intense shaking. This procedure reduces drastically the presence of agglomerates without the disadvantages related to chemical
procedures. Therefore, it is possible to obtain a stable, high efficient catalyst for oxidation reactions, which is also applicable in industrial processes. These properties confer a large range of applications in different target markets.
