Engineering iron single atomic sites with adjacent ZrO2 nanoclusters via ligand-assisted strategy for effective oxygen reduction reaction and high-performance Zn-air batteries

Jie Zhang et al.

Summary: A ligand-assisted strategy was proposed to synthesize single atomic Fe-N-C catalyst derived from Zr-metal-organic frameworks (Zr-MOFs) to enhance ORR activity in Zn-air batteries. The resulting catalyst exhibited comparable ORR activity and outstanding stability due to the optimized Fe-N-4 configuration and strong interface interaction. Density functional theory calculation results further supported the improved ORR process and activity with adjacent ZrO2 nanocluster modulation.
