제목 Fabrication of Iron Doped Cobalt- Vanadate- Cobalt Oxide with Metal-Organic Framework Oriented Nanoflakes for Portable Rechargeable Zinc-Air Batteries
초록 In this paper, a trifunctional electrocatalyst based on iron-doped metal-organic framework aided cobalt vanadate integrated with cobalt oxide (Fe doped MOF CoV@CoO nanoflakes) is synthesized in a simple way. This synthetic method yields a one-of-a-kind nanoflakes heterostructure, a dense porous structure, a high specific surface area, and extraordinarily large active sites. Furthermore, during pyrolysis in a nitrogen atmosphere, the nitrogen element is integrated into the MOF scaffold, considerably improving the electrochemical action. The Fe doped MOF CoV@CoO nanoflakes catalysts produced exhibit outstanding and stable electrochemical activity for ORR, OER, HER, and total water splitting reactions. The rechargeable zinc-air battery is made with Fe doped MOF CoV@CoO nanoflakes as an air cathode, which has outstanding charge-discharge performance and cyclic stability.
