Nanostructured Materials for Heterogeneous Electrocatalytic CO Reduction and their Related Reaction Mechanisms.

The gradually increased concentration of carbon dioxide (CO ) in the atmosphere has been recognized as the primary culprit for the rise of the global mean temperature. In recent years, development of routes for highly efficient conversion of CO has received much attention. This Review describes recent progress on the design and synthesis of solid-state catalysts for the electrochemical reduction of CO . The significance of this catalytic conversion is presented, followed by the general parameters for CO electroreduction and a summary of the reaction apparatus. We also discuss various types of solid catalysts based on their CO conversion mechanisms. We summarize the crucial factors (particle size, surface structure, composition, etc.) determining the performance for electroreduction.
