学术报告摘要

Conversion of Carbon Dioxide through Catalysis and Electrocatalysis

Ocean acidification and climate change are expected to be two of the most difficult scientific challenges of the 21st 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 [1], methanol via selective hydrogenation [2], and hydrocarbons [3]. 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. In the current talk we will present some of our recent results in CO2 conversion via both heterogenerous catalysis [4] and electrocatalysis [5]. We will also discuss the generation of CO2-free H2 [6,7], which is critical for net CO2 reduction. We will conclude by discussing challenges and opportunities in this important research field [8].
