Joule Heating-Driven sp 2-C Domains Modulation in Biomass Carbon for High-Performance Bifunctional Oxygen Electrocatalysis

Highlights The flash Joule heating controllably enhanced sp 2-domains content in various N-doped natural biomass-based carbon. The axial modulation of sp 2-C domains decreased the charge density of pyridinic N and graphitic N configurations resulting into outstanding oxygen electrocatalysis. The ass...

Description
Summary:Highlights The flash Joule heating controllably enhanced sp 2-domains content in various N-doped natural biomass-based carbon. The axial modulation of sp 2-C domains decreased the charge density of pyridinic N and graphitic N configurations resulting into outstanding oxygen electrocatalysis. The assembled Zn-air battery with optimized catalyst achieved an over 1200-h cycle stability with the peak power density of 121 mW cm−2, exceeding the commercial Pt/C + RuO2 catalysts.
