Facile Synthesis of Fe@C Loaded on g-C(3)N(4) for CO(2) Electrochemical Reduction to CO with Low Overpotential

[Image: see text] Electrochemical CO(2) reduction has been acknowledged as a hopeful tactic to alleviate environmental and global energy crises. Herein, we designed an Fe@C/g-C(3)N(4) heterogeneous nanocomposite material by a simple one-pot method, which we applied to the electrocatalytic CO(2) redu...

description [Image: see text] Electrochemical CO(2) reduction has been acknowledged as a hopeful tactic to alleviate environmental and global energy crises. Herein, we designed an Fe@C/g-C(3)N(4) heterogeneous nanocomposite material by a simple one-pot method, which we applied to the electrocatalytic CO(2) reduction reaction (ECR). Our optimized 20 mg-Fe@C/g-C(3)N(4)-1100 catalyst displays excellent performance for the ECR and a maximum Faradaic efficiency (FE) of 88% with a low overpotential of −0.38 V vs. RHE. The Tafel slope reveals that the first electron transfer, which involves a surface-adsorbed *COOH intermediate, is the rate-determining step for 20 mg-Fe@C/C(3)N(4)-1100 during the ECR. More precisely, the coordinating capability of the g-C(3)N(4) framework and Fe@C species as a highly active site promote the intermediate product transmission. These results indicate that the combination of temperature adjustment and precursor optimization is key to facilitating the ECR of an iron-based catalyst.
