摘要：

Carbon dioxide reduction at polycrystalline gold cathode in 0.1M NaHCO3 solution has been re-examined. Like two other group Ib metal cathodes, Ag and Cu, the Au electrode is shown to undergo progressive deactivation during the CO2 electrolysis runs. A periodic, electrochemical activation treatment of the gold electrode is described.
