Abstract
The electrochemical reduction of CO 2 in 0.1 M KOH-methanol electrolyte with a silver electrode was investigated at 248, 258 and 273 K. The main products from CO 2 were carbon monoxide and formic acid. A predominant formation of CO from CO 2 on Ag electrode in the methanol electrolyte was found. The formation efficiency of CO increased at relatively negative potential as temperature decreased, however in contrast, hydrogen formation decreased. The selectivity of CO 2 reduction over H 2 evolution was ameliorated by lowering temperature. From the Tafel plot study, a sufficiently high mass transfer of CO 2 to the electrode was confirmed even in low temperature region. Consequently, it was found that low temperature was extremely effective for the depression of hydrogen formation on Ag electrode in the KOH-methanol.
