英文摘要: The tin electrode with three-dimensional (3D) porous structure was prepared using copper foil as the substrate by electrochemical deposition method for the electrochemical reduction of CO2 into HCOOH. The results indicate that the faradaic efficiency (FE) and the energy conversion efficiency (EE) of CO2 to HCOOH are dependent on the surface roughness of copper foil that can be controlled by the electropolishing time. The prepared 3D tin electrode on the smoothest Cu foil exhibits the highest FE (90%) and EE (50%) at -1.2 V (vs. RHE), which were 1.6 times those on the original copper foil. Meanwhile, the Sn loss ratio of this electrode in the electrochemical process is the lowest, showing good stability. © 2017 Elsevier Ltd. 资助项目: National Natural Science Foundation of China
