Understanding the Improved Activity of Dendritic Sn 1 Pb 3 Alloy for the CO 2 Electrochemical Reduction: A Computational–Experimental Investigation
An alloy of Sn and Pb (Sn1Pb3) was prepared by electrodeposition at large negative current. The deposit is porous, with a honeycomb-like primary structure and a dendritic-like secondary structure. The onset potential for the electroreduction of CO2 is 80 mV lower on dendritic Sn1Pb3 as compared to d...

An alloy of Sn and Pb (Sn1Pb3) was prepared by electrodeposition at large negative current. The deposit is porous, with a honeycomb-like primary structure and a dendritic-like secondary structure. The onset potential for the electroreduction of CO2 is 80 mV lower on dendritic Sn1Pb3 as compared to dendritic Pb. The faradaic efficiency for formate formation is close to 100% in the potential range from −1.16 to −1.56 V vs. SHE. Density functional theory (DFT) computations were performed to uncover the origin of the decrease in the onset potential upon alloying Pb with Sn. Explicit treatment of water molecules in DFT calculations turns out as crucial to achieve an agreement with experimentally measured onset potentials. |
