| Popis: | Using the disulfide bond and carboxyl group in the molecular structure, α-lipoic acid was easily dissolved in the NaOH/urea solution and could be used as a ternary solvent for dissolving cellulose. Through this platform, N, S dual-doped hierarchical porous carbon aerogels (NSHPAs) were successfully obtained via directly dissolving cellulose in this ternary solvent, followed by gelling and carbonization. Because the fabricated carbon materials had a proper structure and a uniform heteroatom doping, their capacitance could reach 329 F g |
