The preparation of a low‐cost, recycled and efficient electrocatalyst for oxygen reduction reaction (ORR) is highly desirable in fuel cells and metal‐air batteries. Herein, γ‐Fe 2 O 3 /reduced Graphene oxide (rGO) nanocomposite is fabricated through a simple and environmentally friendly approach and applied as a high‐performance ORR electrocatalyst. Multiple characterizations confirm the formation of γ‐Fe 2 O 3 /rGO nanocomposite and exhibit well crystal structure, microstructure, and magnetic properties. Furthermore, the cyclic voltammetry and linear sweep voltammetry measurements confirm that the γ‐Fe 2 O 3 /rGO exhibits high ORR catalytic performance for the synergistic effect. Consequently, the obtained γ‐Fe 2 O 3 /rGO might be a promising non‐precious, cheap and recycled catalyst for fuel cells and metal‐air batteries.
