“…Owing to the synergistic effect of porous nanostructures and conductive frameworks from CAs and the high capacitive property provided by electroactive nanomaterials, resulting hybrid aerogels presented superior electrochemical properties. Inorganic materials with high theoretical specific capacity have been widely selected in composites such as nickel sulfide (NiS), [ 136 ] mixed‐valent manganese oxide (MnO x ), [ 137 ] tin (IV) oxide (SnO 2 ), [ 138 ] and metal oxynitride (MO x N y ).

The rapid development of modern industry and excessive consumption of petroleum‐based polymers have triggered a double crisis presenting a shortage of nonrenewable resources and environmental pollution. However, this has provided an opportunity to stimulate researchers to harness native biobased materials for novel advanced materials and applications. Nanocellulose‐based aerogels, using abundant and sustainable cellulose as raw material, present a third‐generation of aerogels that combine traditional aerogels with high porosity and large specific surface area, as well as the excellent properties of cellulose itself. Currently, nanocellulose aerogels provide a highly attention‐catching platform for a wide range of functional applications in various fields, e.g., adsorption, separation, energy storage, thermal insulation, electromagnetic interference shielding, and biomedical applications. Here, the preparation methods, modification strategies, composite fabrications, and further applications of nanocellulose aerogels are summarized, with additional discussions regarding the prospects and potential challenges in future development.

“…It can be summarised that with the addition of MWCNTs, the dimensional stability and thermal stability of aerogels are improved. The dimensional stability of pure CNFs aerogel was quite low because of its low thermal stability [41]. For pure cellulose aerogels, much oxygen‐containing groups were removed after carbonisation process, which caused cellulose aerogels’ volume shrinkage.…”

Carbon aerogels have attracted considerable attention in basic research and for their potential applications in many fields. Here, the fabrication of a magnetic cellulose nanofibre (CNF)/poly(vinyl alcohol) (PVA)/multiwalled carbon nanotubes (MWCNT) carbon aerogel (m-CPMCA) is reported using a simple freeze-drying followed by a carbonisation process, and direct immobilisation of Fe 3 O 4 nanoparticle on the surface of aerogels. The obtained target aerogel has the characteristics of low density (0.098 g/cm 3), high porosity (>90%) and 3D interpenetrating porous structures. Furthermore, m-CPMCA has a surprising compressive strength (about 0.35 MPa) which is obviously higher than many other cellulose-based carbon aerogels. After Carbonization, m-CPMCA exhibits superhydrophobicity, selective absorption for organic solvents and fire-resistance. The m-CPMCA also exhibited a magnetic response and can absorb oil on the water surface and can be actuated by a small magnet. More importantly, the m-CPMCA could be recycled many times by combustion, which showed economic significance. To sum up, the authors believe that m-CPMCA will become a very potential adsorbent for dealing with the increasingly serious problem of organic pollution. 2 Experiments 2.1 Experiment materials All chemicals were of reagent grade and used without further purification.

“…Similarly, reduced-GO (rGO) nanosheets decorated with tin oxide (SnO 2 ) were dispersed into CNF aerogels as a framework for a supercapacitor through a facile hydrothermal reduction process followed by a freeze-drying method. This flexible CNF/rGO/SnO 2 electrode film exhibited high specific capacitance (4.314 F/cm 2 at 1 mA/cm 2 ) in 1 M H 2 SO 4 and excellent capacitance retention of 60.47% at 10 mA/cm 2 after 2000 cycles [ 116 ]. In another study, rGO nanosheets were utilized with CNFs and fabricated rGO/CNF composite films through a combination of filtration and chemical reduction.…”

Sustainable biomass has attracted a great attention in developing green renewable energy storage devices (e.g., supercapacitors) with low-cost, flexible and lightweight characteristics. Therefore, cellulose has been considered as a suitable candidate to meet the requirements of sustainable energy storage devices due to their most abundant nature, renewability, hydrophilicity, and biodegradability. Particularly, cellulose-derived nanostructures (CNS) are more promising due to their low-density, high surface area, high aspect ratio, and excellent mechanical properties. Recently, various research activities based on CNS and/or various conductive materials have been performed for supercapacitors. In addition, CNS-derived carbon nanofibers prepared by carbonization have also drawn considerable scientific interest because of their high conductivity and rational electrochemical properties. Therefore, CNS or carbonized-CNS based functional materials provide ample opportunities in structure and design engineering approaches for sustainable energy storage devices. In this review, we first provide the introduction and then discuss the fundamentals and technologies of supercapacitors and utilized materials (including cellulose). Next, the efficacy of CNS or carbonized-CNS based materials is discussed. Further, various types of CNS are described and compared. Then, the efficacy of these CNS or carbonized-CNS based materials in developing sustainable energy storage devices is highlighted. Finally, the conclusion and future perspectives are briefly conferred.
