Scalable solid-state synthesis of coralline-like nanostructured Co@CoNC electrocatalyst for Zn-air batteries

Abstract

A facile and scalable solid-state synthesis strategy is developed to produce hierarchical coralline-like nanostructured electrocatalysts with cobalt nanoparticles and Co-NX sites for efficient oxygen reduction reaction, opening up an avenue for the mass production of non-precious metal catalysts for metal-air batteries and fuel cells, etc.
