Descripción del proyecto SOLAR FUELS AIM AT STORING SUNLIGHT ENERGY INTO CHEMICALS BONDS JUST USING H2O ALONE OR TOGETHER WITH CO2. THIS STRATEGY WILL ENABLE THE TRANSITION TO A RENEWABLE AND NON-CONTAMINANT ENERGY SOURCE, REDUCING THE GREENHOUSE GASES (GHG) EMISSIONS. IN PARTICULAR, WATER SPLITTING USING RENEWABLE ENERGY SOURCES TO OBTAIN MOLECULAR HYDROGEN AND OXYGEN IS A PROMISING ROUTE TO ACHIEVE A FUTURE WITH LOWER GHG EMISSIONS. HOWEVER, THE LOW EFFICIENCIES OF THIS PROCESS ARE MAINLY ASSOCIATED WITH THE SLOW KINETICS OF THE WATER OXIDATION REACTION. IN THIS CONTEXT, THIS PROJECT IS FOCUSED ON THE DEVELOPMENT, STUDY AND UNDERSTANDING OF AN EFFICIENT PHOTOANODE FOR WATER OXIDATION AND WILL CONTRIBUTE TO THE HOJA DE RUTA PARA EL HIDROGENO VERDE, RECENTLY APPROVED BY THE SPANISH GOVERNMENT.LIWO PROJECT AIMS AT DEVELOPING AN EFFICIENT PHOTOANODE FOR WATER OXIDATION, TO YIELD AND EFFICIENT REDUCTIVE COUNTERPART REACTION. CURRENTLY, THE MAIN FACTOR LIMITING WATER OXIDATION PHOTOANODE PERFORMANCE IS THE MISMATCH BETWEEN THE SLOW WATER OXIDATION KINETICS AND THE FAST RECOMBINATION PROCESSES TAKING PLACE AFTER CHARGE GENERATION UPON LIGHT IRRADIATION. THE NEWLY DEVELOPED WATER OXIDATION PHOTOANODES WILL BE BASED IN THE COUPLING OF FUNCTIONALISED BIMETALLIC NANOCATALYSTS AND A METAL OXIDE PHOTOABSOBER. THE INNOVATIVE LIWO APPROACH TO OVERCOME THE CHALLENGES IN THE FIELD IS: (1) THE USE OF RATIONALLY DESIGNED EARTH-ABUNDANT BIMETALLIC NANOCATALYTS FUNCTIONALISED WITH ORGANIC LIGANDS, WHICH WILL INDUCE SECONDARY COORDINATION EFFECTS STABILISING REACTION INTERMEDIATES AND/OR AIDING PROTON COUPLE ELECTRON PROCESSES NEEDED TO FASTEN WATER OXIDATION CATALYSTS. (2) ATTAINING A GENERAL UNDERSTANDING OF THE STABILISER (LIGAND) INFLUENCE ON THE MORPHOLOGY, SURFACE CHEMISTRY/REDOX PROPERTIES AND PERFORMANCE BY USING DIFFERENT CHARACTERISATION TECHNIQUES, ESPECIALLY IN-SITU SPECTROSCOPIC METHODS TO SHINE LIGHT INTO THE REACTION MECHANISM AND KINETICS OF THE KEY PROCESSES OF SURFACE-FUNCTIONALISED NP. THIS WILL ALLOW A RATIONAL DESIGN AND UPGRADING TOWARD FASTER KINETICS AND HIGHER LONG-TERM STABILITIES. (3) RATIONALLY IMPROVING/TUNING THE ELECTRONIC COMMUNICATION AND AVOIDING/DIMINISHING CHARGE RECOMBINATION PROCESSES BETWEEN OXYGEN EVOLUTION NANOCATALYSTS AND THE PHOTOABSORBERS.IN SUMMARY, LIWO WILL DEVELOP AN EFFICIENT PHOTOANODE FOR WATER OXIDATION AND SIMULTANEOUSLY WILL CONTRIBUTE TO UNRAVEL KEY PARAMETERS TO GUIDE THE DESIGN AND PREPARATION OF NEW AND EFFICIENT PHOTOANODES.
