- Abstract
Lignocellulosic biomass aerogels with relatively high Brunauer-Emmett-Teller (BET) surface area and pore volume were prepared directly from bagasse solutions in the present study. Bagasse was dissolved in DMSO/LiCl, treated with cyclic freezing-thawing processes, and regenerated with water. The resulted bagasse hydrogels were solvent-exchanged to t-butanol and subjected to freeze-drying to obtain the lignocellulosic aerogels. The structure of the aerogels was studied with FTIR, nitrogen absorption, SEM, and XRD. The results showed that the aerogels had sheet-like skeletons interconnected with one another to form three-dimensional networks. The highest BET surface area and total pore volume of the aerogels were 185 m/g and 0.46 cm/g, respectively. By adjusting the concentration of bagasse solution in DMSO/LiCl, the structure of the aerogels could be controlled to some extent.
