Abstract

Inspired by the bio-oxygen oxidation/reduction processes of hemoglobin, iron-based transition metal-like enzyme catalysts have been explored as oxygen reduction reaction (ORR) electrocatalysts. We synthesized a chlorine-coordinated monatomic iron material (FeN₄Cl-SAzyme) via a high temperature pyrolysis method as a catalyst for the ORR. The half-wave potential (E_1/2) was 0.885 V, which exceeded those of Pt/C and the other FeN₄X-SAzyme (X = F, Br, I) catalysts. Furthermore, through density functional theory (DFT) calculations, we systematically explored the better performance reason of FeN₄Cl-SAzyme. This work offers a promising approach toward high-performance single atom electrocatalysts.
