Abstract
Described herein is a simple and versatile synthetic strategy for the preparation of metal-organic frameworks comprising a carbon matrix doped with nitrogen atoms, wherein transition metal ions are bonded to the carbon matrix via the nitrogen atoms. This strategy is applicable for the synthesis of single metal catalysts or multi metal catalysts rich with atomically dispersed metal active sites. The metal-organic frameworks provided herein have numerous application when used in fuel cells.
