Uniformly structured asymmetric coordination Ce single-atom catalysts for stable and efficient oxygen reduction reaction
In oxygen reduction reactions, the symmetric M-N<sub>4</sub> coordination restricts both performance and stability. N<sub>2</sub>O<sub>2</sub>-type catalysts show promise, but their irregular morphology limits practical use. We report a Ce-N<sub>2</sub>O<sub>2</sub>/C single-atom catalyst with uniform morphology synthesized <i>via</i> an oxygen-ligand electrospinning-annealing route, delivering a 0.91 V half-wave potential and 345 h stability in zinc-air batteries, outperforming most asymmetric Ce-based SACs.
