Electrochemical Reduction of Carbon Dioxide to Value-Added Products: The Electrocatalyst and Microbial Electrosynthesis.

The electrochemical reduction of carbon dioxide (CO ) to value-added products obtains great attention and investigation worldwide in recent years. The commercialization of this green process relies on the progress of relating high-performance electrocatalysts and their feasibility with proper reactor design. The microbial electrosynthesis (MES) is an alternative route to reduce CO with electroactive bio-film electrode as catalyst. This review presents the research status and development of cathode catalysts, particularly focusing on the active sites and development tendency, for highly efficient electrochemical reduction CO from personal viewpoint. Some of our results are also presented to exhibit contributions. MES shows a similar process to the typical electrochemical reduction of CO . Their combination is an important trend, and the future research in this field is full of challenges and opportunities.
