<br/>The direct electrochemical CO2 reduction reaction on solid surfaces offers intriguing fundamental scientific as well as practical technical challenges and opportunities. Controlling the selectivity (faradaic efficiency), while maximizing the energy efficiency is key to turn this reaction into a practical process. To achieve this, more fundamental mechanistic work and understanding is needed.<br/> <br/> In this talk, I will highlight some of our recent advances in the understanding of the chemical mechanism of the direct electrochemical reduction of CO2 into value-added fuels and chemicals on metallic surfaces, on non-metallic single-site electrocatalysts and on metallic/non-metallic tandem schemes. DFT based computational mechanistic predictions are tested by experiments and plausible reaction pathways and intermediates and their binding is discussed. Metallic catalysts comprise Cu and Cu-based alloys, non-metallic single site catalysts include high surface area solid carbons with atomically dispersed Metal-nitrogen moieties.
