The choice of polysaccharides is a key aspect of the synthesis of Starbon. Not all polysaccharides have been successfully expanded and carbonised using the Starbon approach, notable examples which have proved impossible being cellulose and chitosan. On the other hand, various starches, alginic acid [10], and pectin [11] all readily form mesoporous structures under the appropriate conditions, and these mesostructures can be successfully translated into carbonaceous materials. Recently, Attard et al. [12] have demonstrated that chitosans can be successfully incorporated into Starbon materials via mixing with alginic acid over a range of compositions, maintaining porosity while, at the same time, incorporating nitrogen.
