“…Due to their controllable density and nano-scale homogeneous microstructure, aerogels possess interesting chemical and physical properties, such as ultra-low density, ultra-high specific surface area, ultra-high porosity, ultralow thermal conductivity and so on. 1 In recent years, many researchers have focused on the investigation of SiO 2 aerogels, 2 resorcinol (R)-formaldehyde (F) aerogels and carbon aerogels (CAs), 3,4 graphene aerogels, 5,6 3D MoS 2 aerogels 7 and so on.…”

“…In different developments, phenolic resins and resorcinol AGs are considered useful sources for porous carbon materials, having some distinct advantages such as high carbon yield and high microporosity of the carbonized materials, even without any activation (Jõul et al, 2018;Li et al, 2019;Jõul et al, 2021). The same tendency has also been observed for lignin-derived materials (Xua et al, 2018;Barra et al, 2022;Wu et al, 2022). Thermal treatment and carbonization of lignin-based resins are attractive topics for the research on porous carbons and carbon fibers (Ren et al, 2021).…”

Lignin is considered a valuable renewable resource for building new chemicals and materials, particularly resins and polymers. The aromatic nature of lignin suggests a synthetic route for synthesizing organic aerogels (AGs) similar to the aqueous polycondensation of resorcinol with formaldehyde (FA). The structure and reactivity of lignin largely depend on the severity of the isolation method used, which challenges the development of new organic and carbon materials. Resorcinol aerogels are considered a source of porous carbon material, while lignin-based aerogels also possess great potential for the development of carbon materials, having a high carbon yield with a high specific surface area and microporosity. In the present study, the birch hydrolysis lignin and organosolv lignin extracted from pine were used to prepare AGs with formaldehyde, with the addition of 5-methylresorcinol in the range of 75%–25%, yielding monolithic mesoporous aerogels with a relatively high specific surface area of up to 343.4 m2/g. The obtained lignin-based AGs were further used as raw materials for the preparation of porous carbon aerogels (CAs) under well-controlled pyrolysis conditions with the morphology, especially porosity and the specific surface area, being dependent on the origin of lignin and its content in the starting material.

“…Lignin is a plentiful and easily accessible biomass regarded as a one-of-a-kind sustainable organic carbon source [ 72 ]. Lignin is a macromolecule with an exceedingly complicated three-dimensional reticulated molecular structure [ 6 , 73 ], containing 40–60% carbon, and is an excellent precursor for porous carbon [ 70 ].…”

Supercapacitors may be able to store more energy while maintaining fast charging times; however, they need low-cost and sophisticated electrode materials. Developing innovative and effective carbon-based electrode materials from naturally occurring chemical components is thus critical for supercapacitor development. In this context, biopolymer-derived porous carbon electrode materials for energy storage applications have gained considerable momentum due to their wide accessibility, high porosity, cost-effectiveness, low weight, biodegradability, and environmental friendliness. Moreover, the carbon structures derived from biopolymeric materials possess unique compositional, morphological, and electrochemical properties. This review aims to emphasize (i) the comprehensive concepts of biopolymers and supercapacitors to approach smart carbon-based materials for supercapacitors, (ii) synthesis strategies for biopolymer derived nanostructured carbons, (iii) recent advancements in biopolymer derived nanostructured carbons for supercapacitors, and (iv) challenges and future prospects from the viewpoint of green chemistry-based energy storage. This study is likely to be useful to the scientific community interested in the design of low-cost, efficient, and green electrode materials for supercapacitors as well as various types of electrocatalysis for energy production.
