“…Pure cellulose aerogel was prepared according to the previous researches as reference [30,31]. The CNF1 and CNF2 suspensions were first diluted with distilled water to a concentration of 0.55% and 0.60%, respectively.…”

“…Most of the micrometer-sized pores (20~50 lm) in original cellulose aerogel [31] (Fig. S3) are filled with silica aerogel, making it a more compacted composite than plain cellulose aerogel.…”

“…Moreover, 3-aminopropyltriethoxysilane (APTES) was grafted on porous cellulose resulting in CO2 adsorption capacity of 1.20 mmol/g, and it retained excellent stability within 20 adsorption-desorption cycles with dry CO2 [203]. Phalimide modified CNF were studied with different loading of amino groups resulting in adsorption values of 5.20 mmol/g [204]. CNF were aminated achieving a high CO2 adsorption capacity of 1.78 mmol/g as well as good regeneration reported above 10 cycles [205].…”

According to the International Energy Agency, biorefinery is “the sustainable processing of biomass into a spectrum of marketable bio-based products (chemicals, materials) and bioenergy (fuels, power, heat)”. In this review, we survey how the biorefinery approach can be applied to highly porous and nanostructured materials, namely aerogels. Historically, aerogels were first developed using inorganic matter. Subsequently, synthetic polymers were also employed. At the beginning of the 21st century, new aerogels were created based on biomass. Which sources of biomass can be used to make aerogels and how? This review answers these questions, paying special attention to bio-aerogels’ environmental and biomedical applications. The article is a result of fruitful exchanges in the frame of the European project COST Action “CA 18125 AERoGELS: Advanced Engineering and Research of aeroGels for Environment and Life Sciences”.

“…Wood, however, is the most commercial natural source of cellulose. Cellulose has unique characteristics, including being a nontoxic material, sustainability, renewability, recyclability, low density (1.6 g/cm 3 ), high aspect ratio, biodegradability, low cost, good mechanical properties, and high specific surface area (150 m 2 /g) [15][16][17]. The cellulose surface consists mainly of hydroxyl groups (-OH functional groups) that can directly interact with modified polymers.…”

“…Surface modification of cellulose with a modified polymer increases its functional properties and makes it more appropriate for a variety of applications [15]. Increasing the reactivity and content of cellulose surface hydroxyl groups so that they react with amine modification of nanocellulose is recommended [17]. It has been suggested that the surface of cellulose could be chemically modified for better CO 2 and PM adsorption by altering the reaction of a functional group from the organo-modified agents and OH on the cellulose surface.…”
