Recent Progress in Electrocatalytic Reduction of CO 2.

A stable life support system in the spacecraft can greatly promote long-duration, far-distance, and multicrew manned space flight. Therefore, controlling the concentration of CO₂ in the spacecraft is the main task in the regeneration system. The electrocatalytic CO₂ reduction can effectively treat the CO₂ generated by human metabolism. This technology has potential application value and good development prospect in the utilization of CO₂ in the space station. In this paper, recent research progress for the electrocatalytic reduction of CO₂ was reviewed. Although numerous promising accomplishments have been achieved in this field, substantial advances in electrocatalyst, electrolyte, and reactor design are yet needed for CO₂ utilization via an electrochemical conversion route. Here, we summarize the related works in the fields to address the challenge technology that can help to promote the electrocatalytic CO₂ reduction. Finally, we present the prospective opinions in the areas of the electrocatalytic CO₂ reduction, especially for the space station and spacecraft life support system. [ABSTRACT FROM AUTHOR]
