Green chemistry and energy conversion are two of the main topics, which will be preferentially addressed in the next years in order to resolve two main problems of the current society: pollution and energy supply. In both areas the main difficulties, which have to be resolved, are related to the poor efficiency of the current catalysts. Although in the past years a lot of work has been dedicated to tackle such problem very little improvements were achieved. Therefore, there is an urgent need of looking for new strategies to overcome the current difficulties. We have seen very recently that Au metal clusters, formed by a few number of atoms, are extremely active catalysts, reaching in some cases enzymatic activities for aerobic oxidation reactions1. At the same time, such clusters, although formed by metal elements, they display semiconductor-like properties, whose band gap can be fine tuned by changing only one atom in the cluster, so that they could be also essayed as photocatalysts. We have indeed observed that clusters can also be used as very efficient photocatalysts for water splitting 2 and the destruction of pollutants. Therefore, the use of these few-atom compounds can open new ways to overcome the current difficulties found with the common catalysts. In this talk it will be presented an overview of the state-of-the art of the catalytic properties of clusters focussing into the fields of self-cleaning, water splitting and aerobic oxidation.
