Quasi-double-star nickel and iron active sites for high-efficiency ...
Although the Faraday efficiencies (FEs) obtained on most of the Ni based single-atom catalysts (Ni–N–C) are satisfactory (generally >90%) for the electrochemical transfer CO 2 to CO, their practical application is still limited by their high overpotentials (>600 mV vs. RHE), which implies a higher energy consumption to drive the CO 2 RR. In this work, we have
