Activation of Carbon Dioxide on Metal and Carbide Surfaces (Invited Talk)

Thursday, November 10, 2016, 5:40 pm, Room 103C

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 [1], methanol via selective hydrogenation [2], 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 [3]. Our research approaches involve the combination of DFT calculations and surface science studies over single crystal surfaces, catalytic evaluations over supported catalysts, and in-situ characterization under reaction conditions. We will also discuss challenges and opportunities in this important research field [4].
