Doped Nanocarbons Derived from Conducting Polymers toward ORR Electrocatalysts

Developing nonprecious electrocatalysts for efficient oxygen reduction reactions (ORR) has aroused increasing interest recently. Doped nanocarbons derived from conducting polymers have emerged as a competitive class of nonprecious‐metal catalysts for the ORR because of their promising catalytic activities, long‐standing stability, and particularly low‐cost and facile preparation at a large scale via simple approaches. This review summarizes the recent progress of the preparation and application as ORR electrocatalysts of heteroatom doped nanocarbons derived from conducting polymers, and transition metal and heteroatom‐codoped nanocarbons from conducting polymers and metal salts. Finally, the challenges and further development of this field are also discussed.
