Résumé :
Using solar radiation to fuel catalytic processes is often regarded as the solution to our energy needs. However, developing effective photocatalysts active under visible light has proven to be difficult, often due to toxicity, instability, and high cost of suitable catalysts. We engineered a novel photoactive nanomaterial obtained by the spontaneous coupling of carbon nanodots with polyoxometalates. While the former are used as photosensitizers, the latter were chosen for their ability to catalyze reductive reactions such as pollutant decomposition and water-splitting. We have found that the electron transfer within the nanohybrids to be extremely efficient and we tested these results on a test-bench photocatalytic application. These results are a cornerstone towards the engineering of a new class of nano-devices, non-toxic, low-cost, and able to carry out solar-driven catalytic processes.
