Researchers at the Chinese Academy of Sciences have developed a novel “chainmail catalyst” composed of carbon-encapsulated FeNi alloy nanoparticles on N-doped graphene nanosheets. This catalyst demonstrates superior performance in oxygen reduction and evolution reactions, particularly enhancing Zn-air battery efficiency. The carbon shell protects the alloy core and facilitates electron transfer, boosting catalytic activity and durability. This innovative design promises advancements in energy storage technologies by improving the performance and lifespan of Zn-air batteries.
