Electrochemical reduction of carbon dioxide (CO2 ) to valuable organic compounds is promising as to recycling of carbon source of CO2 and technical compatibility with systems using renewable energy resources. In recent years, considerable efforts have been devoted to the research field of CO2 conversion using electrocatalysis. This personal account particularly focuses on the recent progress that has been achieved by the Ertl Center and a number of groups in South Korea that becomes one of the larger CO2 emitters. The research trends of catalyst development divided into different categories according to the primary products are presented first. Afterwards, several studies on theoretical calculations and electrolytic reactors are reviewed taking into account the fundamental understanding and feasibility of the CO2 electroreduction. Finally, a perspective on the challenges and needs in achieving the advanced level of research and development is presented.
Keywords: CO2; Electrochemical reduction; Ertl Center; Fuels; South Korea.
