Heteroatom-doped hierarchical porous carbons as high-performance metal-free oxygen reduction electrocatalysts†
Abstract
Heteroatom-doped porous carbons with controllable dopant species were rationally synthesized through a universal polymerization–carbonization strategy, exhibiting considerable activity, superior resistance to methanol, and strong durability towards oxygen reduction in comparison with the Pt/C benchmark, due to the doping effect and unique structural properties.
