摘要：

The IR spectrum of the reduced CO2 was confirmed to be assigned as the adsorbed CO, and received an anomalous ca. 30 cm-1 downward shift by the addition of Ca2+ ions at very small concentration in a 0.1 M sulfuric acid solution. The change of voltammogram characteristics due to Ca2+ ions was observed in the presence of CO2, but not in its absence.
