▎ 摘　　要

NOVELTY - Preparation of nitrogen-doped graphene coated metal core-shell structure electrocatalytic material involves heating and reacting an acidic precursor solution containing potassium ferricyanide(III) and transition metal ions at 25-100degreesC to obtain a product, and calcining at high temperature. USE - Preparation of nitrogen-doped graphene coated metal core-shell structure electrocatalytic material. ADVANTAGE - The method is simple, and does not need complex device, and provides nitrogen-doped graphene coated metal core-shell structure electrocatalytic material with large area and controllable shape. The multi-metal synergistic effect and confinement catalytic mechanism cause excellent electrochemical performance, and can expand the preparation method.
