Artificial Photosynthesis: F rom Multi-Electron Multi Proton Catalysts to Photoelectrochemical Cells.
Mimicking photosynthesis and prod ucing solar fuels is an appealing way to store the huge amount of renewable energy from the sun in a durable and sustainable way. Hydrogen production through water splitting has been set as a primary target for artificial pho tosynthesis [1], which requires the development of efficient and stable cat alytic systems, only based on earth abundant elements, for the reduction of protons from water to molecular hydrogen or the reduction and valorization of carbon dioxide. We will report on our contribution to the development o f various series of catalysts for H2 evolution and CO2 reduction [2-4], inc luding the establishment of methodologies towards the rational benchmarking of their catalytic activity. Besides, we will also describe our effort tow ards the combination of such catalysts with various photoactive motifs for the preparation of photoelectrode materials [5-7] that can be implemented i nto photoelectrochemical [PEC] cells for water splitting [8].
