From Cucurbit7Uril Armor-Equipped Ferrocene to Nitrogen Self-Doped Porous Carbon Hosting Fe Single Atoms and Atomic Clusters for ORR and Zinc-Air Batteries.

Key Points

• This research aims to improve the performance of metal catalysts in oxygen reduction reactions and zinc-air batteries using a novel molecular scaffold.
• Utilized cucurbit[7]uril as a precursor and ferrocene as a metal source for self-assembly.
• Constructed an angstrom-level space-confined precursor (Fc@CB[7]) for better catalyst formulation.
• Coated the complex with ternary eutectic salts to enhance structural characteristics.
• Demonstrated high activity and metal loading of atomically dispersed sites in the Fc@CB[7] complex.
• Achieved significant improvements in electrocatalytic performance for oxygen reduction reactions and battery functionality.
• Observed favorable structural and electrochemical properties due to the unique cage structure of Fc@CB[7].
