Solar-driven integrated carbon capture and utilization: Coupling CO2 electroreduction toward CO with capture or photovoltaic systems

Electrochemical processes have emerged as intriguing strategies for both CO2 capture and valorization, which are needed to combat global warming and climate change. Among other advantages over competing technologies, electrochemical systems can be powered by renewable sources, including solar energy. This review aims at collecting and analyzing the main works proposed in the literature that study the coupling of electrochemical reactors for the conversion of CO2 into carbon monoxide with 1) electrochemical capture systems or 2) solar cells to power them. In addition to the critical analysis of these articles, a brief discussion of future research directions in this field is proposed.
