Nanostructured Materials for Heterogeneous Electrocatalytic CO2 Reduction and their Related Reaction Mechanisms.

The gradually increased concentration of carbon dioxide (CO₂) 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 CO₂ has received much attention. This Review describes recent progress on the design and synthesis of solid-state catalysts for the electrochemical reduction of CO₂. The significance of this catalytic conversion is presented, followed by the general parameters for CO₂ electroreduction and a summary of the reaction apparatus. We also discuss various types of solid catalysts based on their CO₂ conversion mechanisms. We summarize the crucial factors (particle size, surface structure, composition, etc.) determining the performance for electroreduction. [ABSTRACT FROM AUTHOR]
