Background:

Low-cost, earth-abundant electrocatalysts are vital for fuel cells and metal-air batteries.
Non-metal nanocarbons offer advantages like low cost, high conductivity, and durability for oxygen reduction reactions (ORR).
Enhanced ORR activity in nanocarbons is typically attributed to heteroatom doping or defects, though both are often present.

Purpose of the Study:

To provide an overview of recent advances in non-metal carbon-based electrocatalysts for ORR.
To analyze the co-engineering of heteroatom doping and defect induction in nanocarbons.
To discuss the synergistic effects of doping and defects on ORR performance and mechanisms.

Main Methods:

Review and analysis of recent literature on functionalized nanocarbons for ORR.
Discussion of characteristics, performance, and mechanisms of doped and defect-engineered nanocarbons.
Emphasis on the synergistic promotion effects between heteroatom doping and defects.

Main Results:

Heteroatom doping and induced defects significantly enhance ORR activity in non-metal nanocarbons.
Synergistic effects between doping and defects lead to superior electrocatalytic performance.
Detailed analysis of structure-activity relationships and reaction mechanisms.

Conclusions:

Co-engineering of heteroatom doping and defects is a promising strategy for developing high-performance ORR electrocatalysts.
Understanding synergistic promotion effects is key to rational design.
Identifies current challenges and future perspectives for carbon-based electrocatalysts in ORR.
