Highly Selective Electrochemical Reduction of CO2 to Formate on Metal-Free Nitrogen-Doped PC61BM

Abstract

Herein we report the first example of nitrogen-doped fullerene derivative metal-free catalyst for electrochemical reduction of CO2 to formate. The N-doped PC61BM ([6, 6]-Phenyl‑C61-Butyric Acid Methyl Ester) (N-C61) exhibits an excellent activity toward CO2 reduction, reaching a high Faradaic efficiency (FE) of 91.2% for formate production with good stability at a moderate overpotential of 700 mV. A partial formate current density (jHCOO-) of 14.7 mA cm-2 was observed at -1.1 V (vs. RHE), which is larger than most metal-free electrocatalysts. Additionally, the detailed study suggests that graphite N-defects are the most likely active sites for formate formation. This work provides a practical and feasible way to fabricate N-doped fullerene derivative and other heteroatom doped fullerene-based electrocatalysts for electrochemical reduction of CO2.
