“…Electrospun nanofibers can be made from almost unlimited materials, from synthetic to natural polymers, and by adding particles, new materials and composites can be produced [14][15][16][17]. Biomass-derived carbon nanofibers can be produced from a variety of polymers, such as chitin from seafood [18] or fungi [19], lignocellulosic materials [20], gelatin, proteins and from the combination of polymer blends. In order to manipulate the bonding between the fibers of the nanofiber material and improve the overall electrical conductivity, mesoporosity and surface area, often (polyacrylonitrile) PAN-based carbonized nanofibers are used, blended with biopolymers because producing nanofibers from these biopolymers alone is not possible.…”

Electrospun Carbon Nanofibers from Biomass and Biomass Blends—Current Trends

In recent years, ecological issues have led to the search for new green materials from biomass as precursors for producing carbon materials (CNFs). Such green materials are more attractive than traditional petroleum-based materials, which are environmentally harmful and non-biodegradable. Biomass could be ideal precursors for nanofibers since they stem from renewable sources and are low-cost. Recently, many authors have focused intensively on nanofibers’ production from biomass using microwave-assisted pyrolysis, hydrothermal treatment, ultrasonication method, but only a few on electrospinning methods. Moreover, still few studies deal with the production of electrospun carbon nanofibers from biomass. This review focuses on the new developments and trends of electrospun carbon nanofibers from biomass and aims to fill this research gap. The review is focusing on recollecting the most recent investigations about the preparation of carbon nanofiber from biomass and biopolymers as precursors using electrospinning as the manufacturing method, and the most important applications, such as energy storage that include fuel cells, electrochemical batteries and supercapacitors, as well as wastewater treatment, CO2 capture, and medicine.

“…Therefore, lignin/PVA blend is considered a green approach to electrospinning lignin-based CNF. Poly (methyl methacrylate) (PMMA): Using coaxial electrospinning, M Cao et al [66] prepared lignin/PMMA as a core electrospinning solution. Composite nanofibers were formed by a partial combination of the core materials with PVP/SnCl2 shell material.…”

“…Such configuration was able to prepare a lignin fiber inside lignin/ H 3 PO 4 fiber with an average fiber diameter of 1-4 µm. Similarly, a carbon and metal oxide composite nanofiber was prepared from lignin/PMMA and lignin/PMMA/PVP/SnO 2 as core and shell materials, respectively [66]. The fiber diameter (125-200 nm) of the deposited nanofiber was influenced by other spinning parameters and the carbonization process.…”

State of the Art and New Directions on Electrospun Lignin/Cellulose Nanofibers for Supercapacitor Application: A Systematic Literature Review

et al. 2020

View full text Add to dashboard Cite

Supercapacitors are energy storage devices with high power density, rapid charge/discharge rate, and excellent cycle stability. Carbon-based supercapacitors are increasingly attracting attention because of their large surface area and high porosity. Carbon-based materials research has been recently centered on biomass-based materials due to the rising need to maintain a sustainable environment. Cellulose and lignin constitute the major components of lignocellulose biomass. Since they are renewable, sustainable, and readily accessible, lignin and cellulose-based supercapacitors are economically viable and environmentally friendly. This review aims to systematically analyze published research findings on electrospun lignin, cellulose, and lignin/cellulose nanofibers for use as supercapacitor electrode materials. A rigorous scientific approach was employed to screen the eligibility of relevant articles to be included in this study. The research questions and the inclusion criteria were clearly defined. The included articles were used to draw up the research framework and develop coherent taxonomy of literature. Taxonomy of research literature generated from the included articles was classified into review papers, electrospun lignin, cellulose, and lignin/cellulose nanofibers for use as supercapacitor electrode materials. Furthermore, challenges, recommendations, and research directions for future studies were equally discussed extensively. Before this study, no review on electrospun lignin/cellulose nanofiber-based supercapacitors has been reported. Thus, this systematic review will provide a reference for other researchers interested in developing biomass-based supercapacitors as an alternative to conventional supercapacitors based on petroleum products.

The metal oxides/graphene nanocomposites have great application prospects in the fields of electrochemical energy storage and gas sensing detection. However, rational synthesis of such materials with good conductivity and electrochemical activity is the topical challenge for high-performance devices. Here, SnO2/graphene nanocomposite is taken as a typical example and develops a universal synthesis method that overcome these challenges and prepares the oxygen-deficient SnO2 hollow nanospheres/graphene (r-SnO2/GN) nanocomposite with excellent performance for supercapacitors and gas sensors. The electrode r-SnO2/GN exhibits specific capacitance of 947.4 F g−1 at a current density of 2 mA cm−2 and of 640.0 F g−1 even at 20 mA cm−2, showing remarkable rate capability. For gas-sensing application, the sensor r-SnO2/GN showed good sensitivity (~13.8 under 500 ppm) and short response/recovering time toward methane gas. These performance features make r-SnO2/GN nanocomposite a promising candidate for high-performance energy storage devices and gas sensors.
