“…Raman spectra (Figure 5c) further reveal that both amorphous and crystalline carbon coexist in these samples. The intensity ratios of the D to G bands (I D /I G ) are nearly same for these samples, reflecting their similar graphitization degree [41]. To elucidate the crystallinity of N/S-CNF, X-ray powder diffraction (XRD) and Raman spectroscopic investigation were conducted.…”

Exploring inexpensive and highly efficient electrocatalyst to decrease the overpotential of oxygen reduction reaction (ORR) is one of the key issues for the commercialization of energy conversion and storage devices. Heteroatom-doped carbon materials have attracted increasing attention as promising electrocatalysts. Herein, we prepared a highly active electrocatalyst, nitrogen, sulfur co-doped carbon nanofibers (N/S-CNF), via in situ chemical oxidative polymerization of methylene blue on the bacterial cellulose nanofibers, followed by carbonization process. It was found that the type of nitrogen/sulfur source, methylene blue and poly(methylene blue), has significantly influence on the catalytic activity of the resultant carbon nanofibers. Benefiting from the porous structure and high surface area (729 m 2 /g) which favors mass transfer and exposing of active N and S atoms, the N/S-CNF displays high catalytic activity for the ORR in alkaline media with a half-wave potential of about 0.80 V, and better stability and stronger methanol tolerance than that of 20 wt % Pt/C, indicating great potential application in the field of alkaline fuel cell.

“…[213] In both types of electrode materials, the surface charge storage does not need ionic diffusion within the crystalline framework of the material, thus supercapacitors have the advantages of high power density, long cycle life, and high rate capacity. [10,181,214,215] Hence, they have been attracting increasing attention. Recently, many advanced electrode materials have been developed for further improving the performance of supercapacitors, [46,216] where 3D CNF architectures have been proven to be an important candidate.…”

Therefore, it is necessary to develop highperformance energy storage devices for facilitating the effective utilization of intermittent renewable energy sources. [7][8][9] Among varieties of electrochemical energy storage devices, supercapacitors (known as electrochemical capacitors) [10,11] and some rechargeable batteries (lithium-ion batteries (LIBs), lithiumsulfur (Li-S) batteries, and metal-O 2 batteries) [12][13][14][15] are at the frontier, because they can transport high power and store high energy. Nowadays, they play an indispensable role in our daily life by powering numerous portable electronic devices (e.g., cell phones and laptops), hybrid electric vehicles, and large-scale electrical grids. [16][17][18][19] It is well accepted that the performance of energy storage devices mainly depended on their electrode materials. [20,21] Owing to the advantages of large surface area, light weight, good electrical conductivity, and high thermal/ chemical stability, carbon materials have been considered as the most important electrode materials of supercapacitors and rechargeable batteries [8,20,21] Hence, various nanostructured carbons, such as carbon/graphene quantum dots, [22,23] carbon nanofiber (CNFs), [16,24] carbon nanotubes (CNTs), [13,25] graphene [26][27][28][29][30][31][32] carbon nanosheets, [33,34] 3D carbon nanostructures, [35][36][37] and porous carbon, [38,39] have gained great attention. Among these materials, 3D carbon nanomaterials have some advantages. The interlinked architecture not only shortens transport distances for ions in the well-interconnected wall structure, but also provides a continuous pathway endowing for the fast electron transport. [40] Moreover, the structural interconnectivities guarantee higher electrical conductivity and better mechanical stability. [36,41] Thereby, the design and fabrication of various 3D carbonbased nanostructures, including carbon nanotube networks, graphene gels, graphene foams, and 3D CNFs, have been intensively investigated.Over the past few years, there are many reviews summarizing the progress of fabricating 3D carbon-based nanomaterials. For example, Schneider et al. overviewed the recent advance in the synthesis of 3D arranged carbon nanotube architectures. [42] Li et al. reviewed the carbon-based 3D nanostructures for supercapacitors. [36] Cao and Gui et al. comprehensively reviewed the recent progress in synthesis, properties, and energy applications of CNT sponges, aerogels, and hierarchical composites. [43] The development of high-performance electrochemical energy storage devices is critical for addressing energy crises and environmental pollution.

“…Such fascinating performance could be ascribed to the fact that the mesopores and macropores of reduced graphene oxide (rGO) were formed in the fiber and thus accelerate the transportation of electrolyte ions with the aid of larger accessible surface area. Lou et al [92] synthetized the nitrogen-doped carbon nanofibers with hollow nanoparticle-based stucture via a facile carbonization treatment of an electrospun zeolitic imidazolate framework/polyacrylonitrile (ZIF-8/PAN) composite precursor ( Fig. 2a-c).…”

“…Besides the above strategies, researchers have also attempted to synthesize active carbon fibers [23, [88][89][90], hollow carbon fibers [91,92], and nitrogen-doped carbon fibers [77] as electrode materials to improve the electrochemical performance of SCs. Xie et al [88] prepared nitrogen-doped active carbon fibers (ACF@GR) via a facile dip-coating approach with natural silk as template.…”
