Abstract

Oxygen reduction reaction (ORR) is the cornerstone reaction of many renewable energy technologies such as fuel cells and rechargeable metal-air batteries. The Pt-based electrocatalysts exhibit the highest activity toward ORR, but their large implementation is greatly prohibiting by unaffordable cost and inferior durability. During electrode manufacturing and electrochemical reaction, severe aggregation of catalyst nanoparticles induced by size effect further limits the operational performance of electrocatalysts. We report a new strategy for fabrication of active and aggregation-resistant ORR electrocatalyst by caging metal-organic frameworks derived Co-N-C nanocomposites in permeable and porous 3D graphene cages via sprayed drying the mixed colloids of ZIF-67 nanoparticles and graphene oxide, followed by annealing. The 3D graphene cages around Co-N-C nanocomposites not only provide a continuous conductive network for charge transfer, but also prevent the active phase from aggregation during electrode manufacturing and electrochemical reactions. When evaluated as an ORR electrocatalyst, the material exhibited comparable activity but superior stability to commercial Pt/C catalyst in an alkaline electrolyte.
