Abstract

Artificial photosynthesis has been attracting a great deal of attention in the scientific community for decades as an interesting -and feasible- alternative to tackle the major problem related to greenhouse gas emissions into the atmosphere. Thus, the research and development of efficient photocatalytic systems that can drive the uphill reaction to transform the highly stable carbon dioxide molecule into organic fuels, such as formic acid and alcohols, is crucial for our society. In this context, Ru-based complexes have been extensively investigated as electrocatalysts for the carbon dioxide conversion reaction in an electrochemical cell or a hybrid system where it could be coupled with a photocatalyst, typically a Ta-based semiconductor. However, the poor understanding of the reaction mechanism leading to the organic fuel production in such systems still limits their further optimization.
