摘要：
Catalytic CO2 reduction is an emerging domain of sustainable energy. The behavior of polypyridyl ligand to reduce CO2 into value-added products is quite rare. In this study, the Fc-NAP(2) (Fc-NAP(2) = 1,1-bis[1,8-naphthyrid-2-yl]ferrocene) has been employed for CO, reduction in CH,CN/H,0 (90:10, v/v) under homogeneous electrochemical conditions at 1.6 V vs. SCE. The Fc-NAP(2) efficiently produces CO/HCOOH/H-2 from CO2 through proton coupled 2e(-) reduction at an overpotential of 735 mV vs. SCE, wherein the TOF and Faradaic efficiency of CO, H-2, and HCOOH was found to be 8.5 h(-1), 14 h(-1), 4.61 h(-1) and 11.9 +/- 0.09%, 19.4 +/- 0.08%, 10.8 +/- 0.02% respectively at -1.6 V vs. SCE after 3 h of electrolysis.
