Hybrid Systems for the Separation (LHYS)

Design of light-harvesting devices for the photoproduction of chemical energy

The sustainable production of energy is one of the most important scientific and technological challenges facing humanity. For that matter, light-driven photochemical reactions, such as water splitting and CO2 reduction with water, can transform sunlight energy into chemical energy. Designing an efficient organic/inorganic hybrid material that features molecular functional components for light harvesting and catalysis can address the challenges of the field and create a technology breakthrough to convert sunlight into solar fuels.

Metal Organic Frameworks (MOFs) have proven to be very versatile materials over the last 20 years, since it is easy to tune up either, organic linkers or metallic clusters, for a desired application. They have been tested as gas storage materials, separation, catalysts, chemical sensing, and recently they have been tested as photocatalysts(1), where they have shown very promising results. MOFs, ideally, can contain a photosensitizer and a catalyser in the same structure, and by taking advantage of the enormous surface area of the material it is possible to design novel “all-in-one” photocatalysts by choosing different ligands and metallic clusters, obtaining materials with different responses and functionalities.
