Fe/FeC particles encapsulated in hollow carbon nanoboxes for high performance zinc-air batteries.

Zinc-air batteries are recognized for their environmental friendliness and high energy density; however, the slow kinetics of the oxygen reduction reaction (ORR) at the air electrode hinder their commercial viability. The research focuses on synthesizing cubic hollow carbon structures derived from Metal-Organic Frameworks (MOFs), which enhance catalytic performance through improved conductivity and mass transfer. The resulting Fe/FeC/HCNB catalyst demonstrates a half-wave potential of 0.
