Nitrogen-doped holey graphitic carbon from 2D covalent organic polymers for oxygen reduction

Adv Mater. 2014 May 28;26(20):3315-20. doi: 10.1002/adma.201306328. Epub 2014 Mar 24.


Using covalent organic polymer pre-cursors, we have developed a new strategy for location control of N-dopant heteroatoms in the graphitic porous carbon, which otherwise is impossible to achieve with conventional N-doping techniques. The electrocatalytic activities of the N-doped holey graphene analogues are well correlated to the N-locations, showing possibility for tailoring the structure and property of N-doped carbon nanomaterials.

Keywords: conjugated microporous polymers; covalent organic frameworks; metal organic frameworks; metal-free electrocatalysts; oxygen reduction reaction; supercapacitor.
