Regulating the Pore Structure and Heteroatom Doping of Hollow Carbon Fiber Based on a Trifunctional Template Method for High-Performance Lithium-Ion Capacitors

Abstract: Poultry feather is an ideal carbon precursor for energy storage with natural fiber structure and abundant element doping. However, the collapse of the feather’s natural structure and the loss of doped elements during high-temperature treatment limit the application of feather-based active carbon. Herein, Mg­(NO3)2 is introduced as a trifunctional template for morphology supporting, pore creating, and element doping of duck feathers. MgO decomposed from Mg­(NO3)2 can prevent the fiber from melting during carbon… Show more

“…One of the most attractive research themes is utilizing biomass as a carbon material precursor due to abundance, sustainability, and structural stability. [50,51] Huang et al [52] synthesized N/O-doped porous carbon derived from duck feathers. The method of synthesis is unique, which utilized Mg(NO 3 ) 2 as a "trifunctional template" due to its function as a supporting material, in the creation of pores within the structure, and as a source of dopants (Figure 6a).…”
