Abstract: Ocean acidification and climate change are expected to be two of the most difficult scientific challenges of the 21^st century. Converting CO₂ into valuable chemicals and fuels is one of the most practical routes for reducing CO₂ emissions while fossil fuels continue to dominate the energy sector. The catalytic reduction of CO₂ by H₂ can lead to the formation of three types of products: CO through the reverse water-gas shift (RWGS) reaction, methanol via selective hydrogenation, and hydrocarbons through combination of CO₂ reduction with Fischer-Tropsch (FT) reactions. In the current talk we will discuss some of our recent results in CO₂ conversion via both heterogenerous catalysis and electrocatalysis.  Our research approaches involve the combination of DFT calculations and surface science studies over single crystal surfaces, evaluations over supported catalysts, and in-situ characterization under reaction conditions. We will also discuss challenges and opportunities in this important research field.
