Le résumé fourni par la source
Chitin molecules are rich in nitrogen and oxygen elements, with great potential as a carbon-based electrode precursor. However, the direct preparation of chitin-based porous carbon materials (PCMs) often involves multiple complex carbonization processes, which increases the difficulty of large-scale applications, and the specific capacitance also needs to be further improved. Herein, the precursor of porous carbon was obtained by a one-step carbonization from regenerated chitin film after dissolving in lithium chloride and N, N -dimethylacetamide. The Brunauer–Emmett–Teller and morphological assessments showed that the hierarchical porous structure with high specific surface area (2332.0 m 2 g –1 ) could be achieved under the activator of KOH. At 0.5 A g –1, it had a specific capacitance of 255.5 F g –1 . It showed a capacitance retention rate of 91.89% after 5000 cycles, indicating good cycle stability. Therefore, the dissolution and regeneration strategy of chitin provides a new method for the preparation of PCMs used as a supercapacitor electrode.
