With iron phosphate slag as raw material, Fe and P elements were extracted by acid leaching, which was then used to synthesize battery-grade iron phosphate. Meanwhile, activated carbon and carbon nanotubes were introduced to adsorb the residual Fe and P elements in the leachate, and then high-performance Fe/P oxygen reduction catalysts (FP-6) were prepared by calcination. The results show that the FP-6 catalyst exhibits a half-wave potential of-0.037 V (vs.Hg/HgO) in 0.1 mol/L KOH solution, demonstrating excellent oxygen reduction catalytic activity. With FP-6 as the cathode catalyst, the zinc-air batteries can deliver a specific capacity of 780 mAh/g and a power density of 121 mW/cm², and stably cycle for 182 h at a high current density of 5 mA/cm². This study provides a low-cost and sustainable approach for efficient recycling of iron phosphate slag and resource utilization.

以磷铁渣为原料，采用酸浸法提取Fe、P元素合成电池级磷酸铁；同时引入活性炭和碳纳米管对浸出液中残留Fe、P元素进行吸附富集，经焙烧制备得高性能Fe/P氧还原催化剂（FP-6）。结果表明，FP-6催化剂在0.1 mol/L KOH溶液中半波电位达到-0.037 V（vs．Hg/HgO），具有优良的氧还原催化活性；用作锌空气电池正极催化剂时，电池比容量可达780 mAh/g，功率密度为121 mW/cm²，且在5 mA/cm²高电流密度下可稳定循环182 h。本研究为磷铁渣高效回收与资源化再利用提供了低成本、可持续开发的新思路。
