Subsequent carbonization of these COPs led to well-controlled N-doped holey graphitic carbon materials with outstanding performance as electrocatalysts for oxygen reduction in fuel cells and electrode materials in high-performance supercapacitors. The observed electrocatalytic activities of these N-doped holey graphitic carbon materials can be correlated to the N locations in their COP molecular precursors, showing the technological power and importance of the N-location control for tailoring the structure and property of N-doped carbon nanomaterials.
