Macroporous CoO@Co/N-doped graphitic carbon nanosheet arrays were constructed by engineering a mesoporous CoO nanowire core with a highly conductive Co/NGC shell, and this approach will provide a promising strategy to construct highly effective bifunctional electrocatalysts.
The development of low-cost, high-activity, durable non-precious metal bifunctional electrocatalysts is of great importance in the production of hydrogen by water electrolysis.
