“…For antimicrobial cellulose, particularly for use in fibers and fabrics, copper (Cu), zinc (Zn), or noble metals such as silver (Ag), gold (Au), and platinum (Pt) are incorporated [ 60 , 80 ]. For use in CO 2 absorption applications, amine is grafted onto the cellulose network structure via the –OH groups [ 15 , 63 ]. Meanwhile, the crosslinking of chitosan aerogel with polyvinyl alcohol (PVA) has been shown to inhibit aerogel shrinkage by 20% due to supramolecular effect of PVA [ 81 ].…”

“…In the CO 2 adsorption process, the surface chemical structure of the aerogel can be modified via amine functionalization to increase the adsorption process. For instance, an amine functionalized cellulose aerogel was prepared by grafting 3-aminopropyltriethoxysilane onto cellulose gel to increase the nanopores after pore space blockage, thus providing an adsorption capacity of 1.20 mmol/g with dry 1% CO 2 [ 15 ] along with great stability over 20 adsorption–desorption cycles. The reusability of an aerogel for CO 2 adsorption was also demonstrated in a study by Verma et al, who showed that a cellulose-crosslinked polyethyleneimine aerogel was able to absorb CO 2 for up to 10 cycles [ 16 ].…”

“…The density of an aerogel can be as low as 0.004–0.5 g/cm 3 with a high porosity of up to 99.8% and a large specific surface area of 100–1600 m 2 /g [ 11 ]. Due to these properties, the aerogels have been applied as adsorbents of CO 2 [ 12 , 13 , 14 , 15 , 16 ], dyes, and heavy metals [ 2 , 3 , 11 , 17 , 18 , 19 , 20 , 21 , 22 , 23 ], as tissue engineering and blood system scaffolds in the biomedical field [ 3 , 22 , 23 , 24 , 25 , 26 , 27 ], and as materials for thermal insulation [ 4 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 ] and food packaging [ 37 , 38 , 39 , 40 , 41 ]. These versatile materials also exhibit high optical transparencies, low thermal conductivities (down to 12 mW/mK) and low sound speeds [ 42 , 43 ].…”

Porous polysaccharides have recently attracted attention due to their porosity, abundance, and excellent properties such as sustainability and biocompatibility, thereby resulting in their numerous applications. Recent years have seen a rise in the number of studies on the utilization of polysaccharides such as cellulose, chitosan, chitin, and starch as aerogels due to their unique performance for the fabrication of porous structures. The present review explores recent progress in porous polysaccharides, particularly cellulose and chitosan, including their synthesis, application, and future outlook. Since the synthetic process is an important aspect of aerogel formation, particularly during the drying step, the process is reviewed in some detail, and a comparison is drawn between the supercritical CO2 and freeze drying processes in order to understand the aerogel formation of porous polysaccharides. Finally, the current applications of polysaccharide aerogels in drug delivery, wastewater, wound dressing, and air filtration are explored, and the limitations and outlook of the porous aerogels are discussed with respect to their future commercialization.

“…With the increase of APTES content, the CO2 capacity increased to 0.2, 0.37, and 0.61 mmol/g for 17APTES-FS, 23APTES-FS, and 30APTES-FS, respectively. On the other hand, Jiang et al have also conducted a study on the different amine loading times which also affect the CO2 capture capacity [10]. It was observed that with increasing in grafting times, the CO2 adsorption capacity was first increases, then begins to decline at certain times.…”

The increasing emission of carbon dioxide (CO2) to the atmosphere has gained worldwide concern due to its main contribution to climate changes, global warming, and the greenhouse effect. Numbers of technologies have been carried out to remove this hazardous gas from the environment such as absorption, adsorption, membrane separation, cryogenic separation, and the biological process. Due to limitation of the current absorption technique, CO2 adsorption technique using porous solid adsorbents seems to be a potential candidate in capturing CO2. This is due to the advantages such as low regeneration energy requirements, no liquid waste and low cost. Furthermore, amine functionalization such as APTES on solid adsorbents has been progressively study for the usage of enhancing CO2 adsorption. The uses of adsorbents that modified with APTES could enhance the CO2 adsorption performance due to the chemisorption of -NH2 bond from the amine that further improve the CO2 adsorption performance in terms of the CO2 uptake and selectivity. Besides that, functionalization of APTES on adsorbent will also greatly enhance the reactivity towards CO2. In this review, the impact of the diverse amine loadings on different adsorbents and the type of solvent used for APTES-functionalization towards CO2 capture performance was thoroughly elaborated. The suitable reaction conditions and the regenerability of the adsorbents that could significantly affect their CO2 adsorption capacity were also discussed in detail. Other than distributing useful knowledge on the current progress of the APTES-functionalization adsorbents, this review is anticipated to provide benefit for the industrial and academic usage and appeal more attention in this fascinating area of CO2 capture.

“…CNCs were aminated in the gas phase, and 1.59 mmol/g adsorption capacity was achieved which remained high at about 1.5 mmol/g after five cycles compared to untreated CNC aerogel (0.19 mmol/g) [202]. 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].…”

Biorefinery Approach for Aerogels

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”.
