Abstract
The development of active, durable, and low‐cost catalysts to replace noble metal‐based materials is highly desirable to promote the sluggish oxygen reduction reaction in fuel cells. Herein, nitrogen and fluorine‐codoped three‐dimensional carbon nanowire aerogels, composed of interconnected carbon nanowires, were synthesized for the first time by a hydrothermal carbonization process. Owing to their porous nanostructures and heteroatom‐doping, the as‐prepared carbon nanowire aerogels, with optimized composition, present excellent electrocatalytic activity that is comparable to commercial Pt/C. Remarkably, the aerogels also exhibit superior stability and methanol tolerance. This synthesis procedure paves a new way to design novel heteroatom‐doped catalysts.
Carbonize: N, F‐codoped carbon nanowire aerogels were synthesized by a hydrothermal carbonization procedure. The functionalized aerogels present high electrocatalytic activity, superior stability and methanol‐tolerance for ORR in alkaline condition.
