The thesis work focuses on electrochemical and photoelectrochemical catalytic reactions. In particular, it is structured in three sections: 1) The study of novel iron complexes with Schiff base ligands for the electrochemical reduction of carbon dioxide to CO, 2) Photoelectrochemical water oxidation based on nanostructured oxides functionalized with an organic chromophore to produce hybrid photoactive materials, 3) Emergin approaches towards artificial photosynthesis based on electrocarboxylation of organic molecules and photoelectrosynthetic C-H activation of organic substrates.The thesis work focuses on electrochemical and photoelectrochemical catalytic reactions.
