摘要
Abstract
The electrochemical reduction of carbon dioxide was investigated on nickel and platinum electrodes in 0.5 mol dm-3 KHCO3 solutions. The main products were formic acid and carbon monoxide during the electroreduction of CO2, and the Faradaic efficiency for this process depended on the characteristics of the electrode. At ambient temperature and pressure, the Faradaic efficiency was measured to be 8.6% and 2.5% respectively for the production of formic acid and CO with Pt electrode at -1.3V vs Ag/AgCl (saturated KCl). At this same potential, the Faradaic efficiency was measured to be 8.9% and 1.7%respectively with Ni electrode. Tafel plots showed that the electrochemical reduction of CO2 was not limited by the mass transfer process in the range of -0.8 to -1.2V vs Ag/AgCl (saturated KCl).关键词
