| 摘 要： | As natural oil reserves become depleted, attentionwill increasingly focus on alternative energy sources.The energy and raw materials for this are currently de-rived from the burning of coal, with the accompanyingrelease of CO2as a by-product1]. CO2causes…

| Abstract: | The electrochemical reduction of CO2 on a Pb electrode was investigated in 0.1 mol/L KOH/methanol electrolyte at different temperatures and pressures. A graphite electrode was employed as the counter electrode, and an Ag|AgCl (sat. KCl) electrode was used as the reference electrode. The Tafel plots of the products by the electrochemical reduction of CO2 showed that the formation process of HCOOH differed from that of CO and the reduction of CO2was not limited by the diffusion of CO2 in the investigated potential range. Kinetic analysis indicated that the reaction orders were 0.573 for electrochemical reduction of CO2 to CO and 0.671 for CO2 to HCOOH in the cathodic direction. |
