“…Among the CO 2 conversion products, CO could serve as a pivotal platform chemical in the chemical industry and be further converted to various valuable chemicals through established techniques, such as Fischer–Tropsch synthesis. 1,2 Compared to the thermocatalytic reverse water–gas shift (RWGS) reaction for CO 2 -to-CO conversion usually proceeding at high temperatures, 3 CO 2 RR offers significant advantages of mild reaction conditions 4 and direct utilization and storage of renewable energy. 5 To date, great efforts have been devoted to CO 2 RR to produce CO, primarily focusing on catalyst design for achieving high faradaic efficiencies (FEs) and minimizing energy cost.…”
