“…In view of this, Liu et al synthesized amine-terminated highly cross-linked polyphosphazene-functionalized CNTs (PZAA@CNTs) via in situ polycondensation and deposition, and then blended them with lignin to prepare lignin/PZAA@CNT-based CNF mats. 122 Results indicated that PZAA@CNTs could bind to lignin through strong hydrogen bonding forces. The addition of PZAA@CNTs improved the thermal stability and graphitic domains of the lignin/PZAA@CNT-based CNFs mats.…”

“…The reinforcement with carbon nanotubes (CNTs) has been proposed as another method for improving the mechanical properties of CNFs . In this case, the addition of a small amount (1 wt %) of CNTs functionalized with amine-terminated polyphosphazene in the electrospinning solution of lignin/PEO improved the tensile strength of CNFs by 53.2% (reaching 47.5 MPa) and their Young’s modulus by 43.9% (reaching 4.26 GPa).…”

The development of advanced engineering materials from low-cost renewable or waste resources is a key aspect of sustainability. Carbon nanofibers (CNFs) are a one-dimensional form of carbon with diameters in the submicron-and in the nanometer range with wide applicability in energy storage, catalysis, and adsorption. Lignin has recently emerged as a low-cost, biorenewable precursor for the production of CNFs. This comprehensive review presents the state-of-the-art of the manufacture of CNFs from lignin via the electrospinning technique. The first part of this review is concerned with the properties of lignin, the structure and applications of CNFs, especially for energy storage, and the description of the electrospinning method. The second part is focused on the different lignin-based precursor formulations for the manufacture of electrospun CNFs. These include the use of lignin alone or blended with other polymers at various mass ratios (polyacrylonitrile, poly(vinyl alcohol), poly(ethylene oxide), cellulose acetate, poly(ethylene terephthalate), and polyvinylpyrrolidone). In addition, different manufacturing approaches and strategies aiming to enhance the textural, mechanical, and electrochemical properties of CNFs are discussed in connection with their performance in relative applications.

“…Table S2 summarizes the FTIR vibration modes and the corresponding peak positions. For pure HCTP, the characterization absorption peaks at 1211 and 604 cm −1 correspond to P-N and P-Cl bonds, respectively [33]. For pure ANI and HCTP-ANI composite, some typical characterization peaks co-exist at around 1600-1612, 1450-1502, 1400-1480, and 1270-1282 cm −1 , which correspond to -NH 2 , C=C, C-C, and C-N bonds, respectively [34,35].…”

Aqueous Zn-ion hybrid supercapacitors (ZHSCs) hold great potential as next-generation energy storage devices due to their low cost, excellent rate capability, long cycling life, and high safety. Heteroatom-doped hierarchical porous carbons (HD-HPCs) with integrated high specific surface area, multiscale pores, and abundant defects have been regarded as promising cathode materials for ZHSCs. However, the in situ architecture of HD-HPCs with these multiple advantages via a sustainable and controllable method remains an arduous challenge. Herein, a novel molecular engineering strategy was proposed for the in situ construction of N/P/O-doped HD-HPCs via the direct carbonization of multiple-heteroatom-rich hypermolecules. Such a strategy has multiple advantages, including the exclusion of pore-making techniques, activation agents, templates, and complicated and hazard washing processes, demonstrating its green and sustainable properties. The highly active multiple-heteroatom-rich hypermolecular precursors contributed to the formation of abundant micro/mesopores due to the self-abscission of heteroatoms and heteroatom-contiguous carbon atoms at high carbonization temperatures. Consequently, these active structural/compositional features endowed the optimal cathodes with outstanding storage capacities of 139.2 and 88.9 mA h g −1 at 0.5 and 20 A g −1 for aqueous ZHSCs, respectively. They also delivered a superior storage performance in quasi-solid ZHSCs (QS-ZHSCs) with a high specific capacity of 111.5 mA h g −1 at 0.5 A g −1 . Superior energy/power densities and long cycling stability were also achieved for aqueous and QS-ZHSCs. The theoretical calculation confirmed the synergetic effects of multiple-atom doping on enhancing the electronic conductivity and reducing the energy barrier between Zn ions and carbon, which promote the Zn-ion adsorption capability. These findings shed fresh light on the straightforward manufacture of superior HD-HPCs for electrochemical energy storage.
