Modulation of Single Atomic Co and Fe Sites on Hollow Carbon Nanospheres as Oxygen Electrodes for Rechargeable Zn–Air Batteries
Abstract
<jats:title>Abstract</jats:title><jats:p>Efficient bifunctional electrocatalysts for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) are required for metal air batteries, to replace costly metals, such as Pt and Ir/Ru based compounds, which are typically used as benchmarks for ORR and OER, respectively. Isolated single atomic sites coordinated with nitrogen on carbon supports (M‐N‐C) have promising performance for replacement of precious metal catalysts. However, most of monometallic M‐N‐C catalysts demonstrate unsatisfactory bifunctional performance. Herein, a facile way of preparing bimetallic Fe and Co sites entrapped in nitrogen‐doped hollow carbon nanospheres (Fe,Co‐SA/CS) is explored, drawing on the unique structure and pore characteristics of Zeolitic imidazole frameworks and molecular size of Ferrocene, an Fe containing species. Fe,Co‐SA/CS showed an ORR onset potential and half wave potential of 0.96 and 0.86 V, respectively. For OER, (Fe,Co)‐SA/CS attained its anodic current density of 10 mA cm<jats:sup>–2</jats:sup> at an overpotential of 360 mV. Interestingly, the oxygen electrode activity (Δ<jats:italic>E</jats:italic>) for (Fe,Co)‐SA/CS and commercial Pt/C‐RuO<jats:sub>2</jats:sub> is calculated to be 0.73 V, exhibiting the bifunctional catalytic activity of (Fe,Co)‐SA/CS. (Fe,Co)‐SA/CS evidenced desirable specific capacity and cyclic stability than Pt/C‐RuO2 mixture when utilized as an air cathode in a homemade Zinc‐air battery.</jats:p>
