A review on the emerging applications of cellulose, cellulose derivatives and nanocellulose in carbon capture

Nanocellulose from Agricultural Wastes: Products and Applications—A Review

“…Two of the main strategies for CO 2 adsorption implies the nanocellulose chemical modification or inclusion of inorganic particles into nanocellulose; these nanomaterials, especially functionalized nanocelullose aerogels, can be employed as adsorbents or constituents of membranes to retain CO 2 selectively [127]. In this sense, nanocellulose has been employed to take part of physical (hydrogen bonds) or chemical (borax, epichlorohydrin or glutaraldehyde) cross-linked hydrogels that can be transformed to aerogels by freeze-drying cycles.…”

Amine-functionalized porous organic polymers for carbon dioxide capture

“…Besides PIMs, there have been reports on other types of processible polymer sorbents such as cellulose acetate 160 and matrimid. 161 However, these polymers are not categorized as a porous organic polymer because the porosity in these polymers is predominately macroporous (>50 nm).…”

Liquefiable biomass-derived porous carbons and their applications in CO2capture and conversion

“…CNCs usually have higher crystallinity, shorter length (<100 nm) and higher dispersion than CNFs, which are widely used to enhance the failure strain of composites. 156,157 Studies focusing on the use of CNFs and CNCs as CO 2 adsorbents and catalysts have main strategies including: (i) the chemical modification of nanocellulose (amino-modified) [158][159][160] and (ii) the incorporation of inorganic particles into nanocellulose (e.g., silica, zeolite, carbon). 152,161,162 Bacterial nanocellulose is a porous nanoscale biopolymer synthesized by microbial fermentation.…”
