HyMAP is the acronym for Hybrid Materials for Artificial Photosynthesis, the title of the ERC Consolidator Grant awarded to Dr. V. A. de la Peña O’Shea in the 2014 call. The challenging process of Artificial Photosynthesis is based on the use of solar light to convert CO2 and water into energy-useful compounds like CO, methane, methanol and hydrogen – just as green plants do, but replacing the sugars they produce by those simpler compounds. HyMAP aims at developing a new generation of hybrid organo-inorganic materials that are able to efficiently promote, by photocatalytic and photoelectrochemical reactions, the chemical transformations ecompassed in artificial photosynthetic processes. In order to reach this goal, the HyMAP team investigates materials and processes and different scales – from nanoscaled catalysts to pilot-plant reactors.
