Non-pyrolysis prepared naphthalene diimide-based bimetallic phthalocyanine covalent organic polymers@carbon nanotube nanocomposites for oxygen reduction

, which is superior to that of 20% Pt/C. In addition, CoFe/NDI-COP@CNTs show exceptional methanol resistance and electrochemical stability. This work provides new insights for the non-pyrolysis preparation of metal-doped carbon electrocatalysts with well-defined active sites from COPs.
