Different metal foams including Cu foam, ox-re Cu foam, and Sn foam were prepared by electrodeposition, and characterized by SEM, TEM and XRD. Electrochemical reduction of CO2 at these metal foams were studied. These metal foams have significantly different catalytic selectivity and activity from smooth metal foil electrode. The different surface property and hierarchical porosity of these foam structures are proposed to explain their unique behaviors. Mechanistic pathways are proposed which are supported by the available experimental results and existing computational studies.


Dan Liu completed his Bachelor of Science in Chemistry at School of Chemistry and Chemical Engineering, Nanjing University, China in 2011. He then applied for graduate studies at Brown University in the fall of 2011, and joined Prof. Tayhas Palmore’s research group in the summer of 2012. Since then, he has worked on electrochemistry of various materials, including catalytic materials for CO2 reduction and electrode materials for Na-ion batteries. He is currently a fourth-year graduate student in the Department of Chemistry.
