Abstract
The electrochemical reduction of CO2 was studied with galvanostatic (5 mA cm−2) electrolysis at a copper electrode between 0 and 40 °C. The production of CH4 and C2H4 was confirmed by GC with 4 different columns. The faradaic efficiency of CH4 formation was about 65% at 0 °C and dropped with an increase of temperature, whereas that of C2H4 formation rose to ca. 20% at 40 °C.Keywords
