“…According to IUPAC classification, IL‐Fe‐PAN‐900‐0.25, IL‐Fe‐PAN‐900‐0.50, IL‐Fe‐PAN‐900‐0.75 and IL‐Fe‐PAN‐800‐0.75 all present a type‐I sorption isotherm, revealing the main existence of microporous structure . Furthermore, IL‐Fe‐PAN‐1000‐0.75 differently exhibits a hysteresis loop at the relative pressure of 0.48–1.0, indicating a type‐IV sorption isotherm and the presence of micropores and mesopores . Pore‐size distribution curves (on basis of density functional theory) of IL‐Fe‐PAN‐T‐ns in Figure d further prove these analysis.…”

Practical applications of Zn-airb atteriesa re usually limited by sluggish kinetics of oxygen reduction reaction. Replacing Pt-basedc atalysts with convenient, efficient and low-cost materials to boost oxygen reductionr eaction is highly desirable. Herein, ac lass of FeÀNc o-doped carbon nanofibers is successfully synthesized by pyrolysis of polyacrylonitrile/metal-containing ionic liquid-based electrospun films. The ionic liquidsa ct as porogen to provide multiscale pores as well as activator to bring carbon nanofibers active sites. The catalyst possessing appropriate actives ites and unique 3D porous architecture exhibits remarkable longterm stability and electrocatalytic activity.P articularly,t he catalystm aintains as hape of membrane after carbonization, manifesting its direct use as air electrode without binders. It is notable that an all solid-state Zn-air battery based on the carbon nanofibers exhibitsg ood flexibility,i ndicating its promising applicationasw earable devices.

“…However, the porous structure needs to be also considered from the kinetic implication, which is associated with the dynamic system with repeated adsorption and desorption cycles of flowing ions at the specific voltage or current. Accordingly, many studies have been carried out to construct the proper porous structures of activated carbons according to the sizes of given sodium and chloride ions . It is well known that the nanoporous structure interconnected with appropriate mesopores was suitable for the efficient utilization of electrode surfaces .…”

The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/adma.201803444. Electrochemical sodium storage and capture are considered an attractive technology owing to the natural abundance, low cost, safety, and cleanness of sodium, and the higher efficiency of the electrochemical system compared to fossil-fuel-based counterparts. Considering that the sodium-ion chemistry often largely deviates from the lithium-based one despite the physical and chemical similarities, the architecture and chemical structure of electrode materials should be designed for highly efficient sodium storage and capture technologies. Here, the rational design in the structure and chemistry of carbon materials for sodium-ion batteries (SIBs), sodium-ion capacitors (SICs), and capacitive deionization (CDI) applications is comprehensively reviewed. Types and features of carbon materials are classified into ordered and disordered carbons as well as nanodimensional and nanoporous carbons, covering the effect of synthesis parameters on the carbon structure and chemistry. The sodium storage mechanism and performance of these carbon materials are correlated with the key structural/chemical factors, including the interlayer spacing, crystallite size, porous characteristics, micro/nanostructure, morphology, surface chemistry, heteroatom incorporation, and hybridization. Finally, perspectives on current impediment and future research directions into the development of practical SIBs, SICs, and CDI are also provided. Nanostructured Carbon

“…29,43 The relative content of pyrrolic N decreased, but the content of quaternary N increased, indicating that quaternary N sites are more stable than pyrrolic N sites at high temperature, consistent with previous studies. 44,45 A higher quaternary N content may enhance the electronic conductivity because of its specic chemical structure. 6 In addition, amino cyclization may occur at high temperature.…”
