Ternary Doped Porous Carbon Nanofibers with Excellent ORR and OER Performance for Zinc-air Battery

Abstract

Oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) play an important role in the air electrode reactions of rechargeable Zn-air battery. However, the noble metal-based catalysts for ORR and OER always suffer from high cost and poor stability. Carbon-based materials with many advantages such as low cost, good conductivity, large specific surface area and considerable durability, are considered as promising alternatives to noble metal-based catalysts. In particular, the doping of heteroatoms into carbon has been proven to be an effective method to improve catalytic performance. Herein, we synthesized the N, F, P ternary doped macro porouscarbon fibers (NFPC) as bifunctional catalyst for secondary Zn-air battery for the first time via electrospinning method with subsequent thermal annealing. The evenly distribution of heteroatoms in the macroporous carbon fibers induced the greatly improved catalytic efficiency towards ORR and OER, and show exceptional properties in the rechargeable Zn-air system.
