AB - The development of high-performance bifunctional electrocatalysts is essential for advancing rechargeable zinc–air batteries (ZABs), particularly to overcome the sluggish kinetics of oxygen reduction (ORR) and oxygen evolution (OER) reactions at the air electrode. Here we propose a bifunctional Fe<inf>2</inf>Mo<inf>3</inf>O<inf>8</inf>/MoS<inf>2</inf> (Fe-Mo) catalyst anchored to the surface of carbon cloth (CC) with leaf-like Co<inf>3</inf>O<inf>4</inf> as the Fe<inf>2</inf>Mo<inf>3</inf>O<inf>8</inf>/MoS<inf>2</inf>@ Co<inf>3</inf>O<inf>4</inf> /CC (Fe-Mo@Co-CC) electrode with effective bifunctional catalytic properties. A high-temperature annealing process is employed to synthesize Fe<inf>2</inf>Mo<inf>3</inf>O<inf>8</inf> on the surface of MoS<inf>2</inf> sheets. Density functional theory (DFT) calculations reveal a favorable Gibbs free energy change of −546.25 kcal mol¹, indicating enhanced annealing reaction thermodynamics and improved catalytic efficiency upon Fe<inf>2</inf>Mo<inf>3</inf>O<inf>8</inf> incorporation. The leaf-like Co<inf>3</inf>O<inf>4</inf> structure offers a large surface area, contributing to an increased number of accessible active sites. Moreover, the collective effects between Fe-Mo and Co<inf>3</inf>O<inf>4</inf> forms an efficient interface that promotes rapid electron and ion transport, thereby enhancing the overall bifunctional electrocatalytic activity. When applied in liquid-phase ZABs, the Fe-Mo@Co-CC delivers a high peak power density of 105.4 mW cm<sup>−2</sup> and maintains excellent cycling stability over 5000 cycles. The study emphasizes the significance of the collective effects of transition metal components and the c
