Abstract

The past few decades have witnessed significant advances in our understanding of the synthesis routes and development of electrocatalysts for the reduction of CO2 to hydrocarbons. It is also notable that the research field related to the Origin of Life theory starts to recognize the significance of electrochemical CO2 reduction by metal-sulfide minerals as the primary step for organic carbon synthesis. In this chapter, we describe recent progress in the development of catalysts for CO2 reduction in electrochemical systems, particularly from the viewpoint of the Origin of Life theory, and discuss the perspectives related to the evolutional origin of carbon monoxide dehydrogenases (CODHs), known as one of the most active natural enzymes for CO2 reduction.
